Hello,
Here is a new version of the patch series adding support for the
BeagleV in Buildroot.
Here are the changes compared the first version:
- Dropped the first two patches, as they have been merged upstream.
- In the OpenSBI patch adding options to enable/disable image
installation, take into account the reviews from Bin Meng how the
ordering of options + a typo in the fw_jump option prompt.
- In the beaglev_defconfig patch itself, use .out instead of .flash
for the ready-to-be-flashed OpenSBI/U-Boot image, to be consistent
with the extension documented by upstream, and also used by other
firmware files for this platform.
- In the beaglev_defconfig patch itself, fix the post-build script to
work in out-of-tree situation, as pointed out by Frank Hunleth.
- Fix the naming of the platform to BeagleV and the naming of the SoC
to JH7100.
- Add support for building the other firmware files that are used in
the boot process of the BeagleV: secondboot and ddrinit. To keep
the patch series easier to merge, this is done as a separate step
from the main defconfig addition. Building those two firmware files
requires a bare-metal RISC-V 64-bit toolchain, so a host package is
created for that.
The branch at:
https://github.com/tpetazzoni/buildroot/commits/beaglev
has been updated accordingly.
Best regards,
Thomas Petazzoni

Until now, whenever a BR2_TARGET_OPENSBI_PLAT value was specified,
opensbi.mk was assuming that both fw_jump and fw_dynamic would be
produced. However, this is not the case: the OpenSBI per-platform
config.mk can decide which image to build.
As an example, the config.mk for VIC7100-based BeagleV only enables
producing the fw_payload image.
This commit adds three options to enable the installation of images:
one for fw_jump, one for fw_dynamic, one for fw_payload.
The options for fw_jump and fw_dynamic are "default y" when
BR2_TARGET_OPENSBI_PLAT is not empty, to preserve existing behavior.
The option for fw_payload is forcefully selected when either Linux or
U-Boot are selected as payloads.

+
+The default fdt_addr_r of 0x88000000 doesn't work, the kernel never
+boots. Using 0x90000000 works fine.
+
+Since it would overlap with the kernel_comp_addr_r area, this one is

+BeagleV
+=======
+
+BeagleV is a low-cost RISC-V 64-bit based platform, powered by a
+Starfive JH7100 processor. The current defconfig in Buildroot has been
+tested with the JH7100 chip used on the beta version of the BeagleV
+board.
+
+How to build
+============
+
+$ make beaglev_defconfig
+$ make
+
+Build results
+=============
+
+After building, output/images contains:
+
++ Image
++ fw_payload.bin
++ fw_payload.bin.out
++ fw_payload.elf
++ rootfs.ext2
++ rootfs.ext4
++ sdcard.img
++ u-boot.bin
+
+The two important files are:
+
+ - fw_payload.bin.out, which is the bootloader image, containing
+ both OpenSBI and U-Boot.
+
+ - sdcard.img, the SD card image, which contains the root filesystem,
+ kernel image and Device Tree.
+
+Flashing the SD card image
+==========================
+
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Preparing the board
+===================
+
+Connect the Beagle-V fan to the 5V supply (pin 2 or 4 of the GPIO
+connector) and GND (pin 6 of the GPIO connector).
+
+Connect a TTL UART cable to pin 8 (TX), 10 (RX) and 14 (GND).
+
+Insert your SD card.
+
+Power-up the board using an USB-C cable.
+
+Flashing the bootloader
+=======================
+
+The bootloader pre-flashed on the Beagle-V has a non-working
+fdt_addr_r environment variable value, so it won't work
+as-is. Reflashing the bootloader with the bootloader image produced by
+Buildroot is necessary.
+
+When the board starts up, a pre-loader shows a count down of 2
+seconds, interrupt by pressing any key. You should reach a menu like
+this:
+
+--------8<----------
+
+bootloader version:210209-4547a8d
+ddr 0x00000000, 1M test
+ddr 0x00100000, 2M test
+DDR clk 2133M,Version: 210302-5aea32f
+0
+***************************************************
+*************** FLASH PROGRAMMING *****************
+***************************************************
+
+0:update uboot
+1:quit
+select the function:
+
+--------8<----------
+
+Press 0 and Enter. You will now see "C" characters being
+displayed. Ask your serial port communication program to send
+fw_payload.bin.out using the Xmodem protocol.
+
+After reflashing is complete, restart the board, it will automatically
+start the system from the SD card, and reach the login prompt.

This commit adds a new package for a prebuilt bare-metal toolchain for
RISC-V 64-bit. Indeed, some bootloader/firmware for the BeagleV (and
potentially later for other platforms?) do not build with a
Linux-capable toolchain.
This uses a pre-built toolchain from SiFive, precompiled for x86-64,
so all packages using this toolchain must have the appropriate
BR2_HOSTARCH dependency.
This package is modeled after package/arm-gnu-a-toolchain/, which
package a pre-built ARM32 bare-metal toolchain.

This packages allows to build the first stage bootloader used on the
BeagleV, which is used even before the DDR initialization and
OpenSBI/U-Boot. Yes, "secondboot" is strange for what is the first
stage bootloader, but that's the upstream name.

+Flashing low-level bootloaders
+==============================
+
+The BeagleV comes pre-flashed with functional low-level bootloaders
+(called "secondboot" and "ddrinit"). Re-flashing them is not necessary
+to use this Buildroot defconfig. However, for the sake of
+completeness, Buildroot builds and provides those low-level bootloader
+images.
+
+You can flash them as follows:
+
+ - In the same "pre-loader" menu as the one used above, instead of
+ entering 0 or 1, enter the magic "root at s5t" string. This enters the
+ "expert" features.
+
+ - Then, press 0 and send over X-modem the

+
+ - Then, press 1 and send over X-modem the

+
+Note that the reflashing mechanism itself relies on those low-level

+through a recovery process. This requires wiring up to a separate

Hello,
Here is a new version of the patch series adding support for the
BeagleV in Buildroot.
Here are the changes compared the first version:
- Dropped the first two patches, as they have been merged upstream.
- In the OpenSBI patch adding options to enable/disable image
installation, take into account the reviews from Bin Meng how the
ordering of options + a typo in the fw_jump option prompt.
- In the beaglev_defconfig patch itself, use .out instead of .flash
for the ready-to-be-flashed OpenSBI/U-Boot image, to be consistent
with the extension documented by upstream, and also used by other
firmware files for this platform.
- In the beaglev_defconfig patch itself, fix the post-build script to
work in out-of-tree situation, as pointed out by Frank Hunleth.
- Fix the naming of the platform to BeagleV and the naming of the SoC
to JH7100.
- Add support for building the other firmware files that are used in
the boot process of the BeagleV: secondboot and ddrinit. To keep
the patch series easier to merge, this is done as a separate step
from the main defconfig addition. Building those two firmware files
requires a bare-metal RISC-V 64-bit toolchain, so a host package is
created for that.
The branch at:
https://github.com/tpetazzoni/buildroot/commits/beaglev
has been updated accordingly.
Best regards,
Thomas Petazzoni

Until now, whenever a BR2_TARGET_OPENSBI_PLAT value was specified,
opensbi.mk was assuming that both fw_jump and fw_dynamic would be
produced. However, this is not the case: the OpenSBI per-platform
config.mk can decide which image to build.
As an example, the config.mk for VIC7100-based BeagleV only enables
producing the fw_payload image.
This commit adds three options to enable the installation of images:
one for fw_jump, one for fw_dynamic, one for fw_payload.
The options for fw_jump and fw_dynamic are "default y" when
BR2_TARGET_OPENSBI_PLAT is not empty, to preserve existing behavior.
The option for fw_payload is forcefully selected when either Linux or
U-Boot are selected as payloads.

+Subject: [PATCH] include/configs/starfive-vic7100: adjust fdt_addr_r
+
+The default fdt_addr_r of 0x88000000 doesn't work, the kernel never
+boots. Using 0x90000000 works fine.
+
+Since it would overlap with the kernel_comp_addr_r area, this one is
+moved 16 MB further, at 0x91000000.

+BeagleV
+=======
+
+BeagleV is a low-cost RISC-V 64-bit based platform, powered by a
+Starfive JH7100 processor. The current defconfig in Buildroot has been
+tested with the JH7100 chip used on the beta version of the BeagleV
+board.
+
+How to build
+============
+
+$ make beaglev_defconfig
+$ make
+
+Build results
+=============
+
+After building, output/images contains:
+
++ Image
++ fw_payload.bin
++ fw_payload.bin.out
++ fw_payload.elf
++ rootfs.ext2
++ rootfs.ext4
++ sdcard.img
++ u-boot.bin
+
+The two important files are:
+
+ - fw_payload.bin.out, which is the bootloader image, containing
+ both OpenSBI and U-Boot.
+
+ - sdcard.img, the SD card image, which contains the root filesystem,
+ kernel image and Device Tree.
+
+Flashing the SD card image
+==========================
+
+$ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Preparing the board
+===================
+
+Connect the Beagle-V fan to the 5V supply (pin 2 or 4 of the GPIO
+connector) and GND (pin 6 of the GPIO connector).
+
+Connect a TTL UART cable to pin 8 (TX), 10 (RX) and 14 (GND).
+
+Insert your SD card.
+
+Power-up the board using an USB-C cable.
+
+Flashing the bootloader
+=======================
+
+The bootloader pre-flashed on the Beagle-V has a non-working
+fdt_addr_r environment variable value, so it won't work
+as-is. Reflashing the bootloader with the bootloader image produced by
+Buildroot is necessary.
+
+When the board starts up, a pre-loader shows a count down of 2
+seconds, interrupt by pressing any key. You should reach a menu like
+this:
+
+--------8<----------
+
+bootloader version:210209-4547a8d
+ddr 0x00000000, 1M test
+ddr 0x00100000, 2M test
+DDR clk 2133M,Version: 210302-5aea32f
+0
+***************************************************
+*************** FLASH PROGRAMMING *****************
+***************************************************
+
+0:update uboot
+1:quit
+select the function:
+
+--------8<----------
+
+Press 0 and Enter. You will now see "C" characters being
+displayed. Ask your serial port communication program to send
+fw_payload.bin.out using the Xmodem protocol.
+
+After reflashing is complete, restart the board, it will automatically
+start the system from the SD card, and reach the login prompt.

This commit adds a new package for a prebuilt bare-metal toolchain for
RISC-V 64-bit. Indeed, some bootloader/firmware for the BeagleV (and
potentially later for other platforms?) do not build with a
Linux-capable toolchain.
This uses a pre-built toolchain from SiFive, precompiled for x86-64,
so all packages using this toolchain must have the appropriate
BR2_HOSTARCH dependency.
This package is modeled after package/arm-gnu-a-toolchain/, which
package a pre-built ARM32 bare-metal toolchain.

This packages allows to build the first stage bootloader used on the
BeagleV, which is used even before the DDR initialization and
OpenSBI/U-Boot. Yes, "secondboot" is strange for what is the first
stage bootloader, but that's the upstream name.

+
+Flashing low-level bootloaders
+==============================
+
+The BeagleV comes pre-flashed with functional low-level bootloaders
+(called "secondboot" and "ddrinit"). Re-flashing them is not necessary
+to use this Buildroot defconfig. However, for the sake of
+completeness, Buildroot builds and provides those low-level bootloader
+images.
+
+You can flash them as follows:
+
+ - In the same "pre-loader" menu as the one used above, instead of
+ entering 0 or 1, enter the magic "root at s5t" string. This enters the
+ "expert" features.
+
+ - Then, press 0 and send over X-modem the
+ bootloader-BEAGLEV-buildroot.bin.out file.
+
+ - Then, press 1 and send over X-modem the
+ ddrinit-2133-buildroot.bin.out.
+
+Note that the reflashing mechanism itself relies on those low-level
+bootloaders, so if you flash non-working versions, you'll have to go
+through a recovery process. This requires wiring up to a separate
+debug UART, whose pins are located near the HDMI connector. See
+https://wiki.seeedstudio.com/BeagleV-Update-bootloader-ddr-init-boot-uboot-Recover-bootloader/
+section "Recover the bootloader" for more details.

Could we not get an official GCC build instead of SiFives custom toolchain?

Out of interest, why is that? For the ARM32 case it was a question of
32bit / 64bit, but that does not seem to be the issue here?
Just crappy firmware or are there any deeper differences between a bare
metal and Linux toolchain on riscv64?

What do you call an "official GCC build" ? A toolchain built by
Buildroot from source ? Buildroot can only build a single toolchain,
which is Linux capable. Buildroot does not know how to build a separate

It is not yet 100% sure what's going on. The firmware clearly doesn't
build with a Linux toolchain. I've done a bit of work to try to get it
to build, by adding -ffrestanding -nostdinc, but it does include a few
standard headers (stdint.h for example). Once this was fixed, the build
system of the firmware uses a specific gcc spec file, called nano.spec,
which isn't available except in their bare-metal toolchain.
So for now, I opened a bug report at
https://github.com/starfive-tech/beagle_ddrlnit/issues/4, and decided
to go on with building this with the recommended bare-metal toolchain.
Best regards,
Thomas

I just meant something from upstream GCC and not a vendor.

But where is "upstream GCC" providing pre-compiled bare-metal toolchains?

This is not something that needs to be noted in the patch, but I wanted
to make people aware that the instructions currently recommed using
SecureCRT as the terminal emulator. I know many including myself would
not want to use a trial version of commercial software.
The author of the guide, Lakshantha, told me that he could not transfer
the vic_second_boot.boot.bin using xmodem in minicom when connected via
the debug header. After he uploaded the file using minicom, he would
type "do 0x18000000", but there would be no response. It did however
work ok in SecureCRT.
Lakshantha will be back on May 6 but in the meantime I would welcome any
suggestions. I figure there must be some difference in the default
behavior of securecrt vs minicom.
thanks,
drew

Thanks for the additional detail. I indeed missed that the recovery
mechanism seems to not work with terminal emulator others than this
commercial software.
I have been lucky that for me the secondBoot and ddrInit just worked,
so I was able to reflash them using the normal flashing solution (from
the standard UART).
Best regards,
Thomas

nits: please put secondBoot first in this patch series
I expect the ddrInit firmware is no longer necessary when upstream
U-Boot supports SPL for this target. For the time being, this patch
looks good.

The only reason why beaglev-ddrinit appears before beaglev-secondboot
in this series is because beaglev-ddrinit sorts before
beaglev-secondboot by alphabetic ordering.

Yes, indeed.
