Re: [R-CAR][Lager Board - Bringup with linux kernel4.3]

[조창환]

 Hello...

 I have problem during bring up R-CAR H2 Lager Board with linux4.3.

 The step I did is below

 1) downloaded linux and uboot from below link.

 In kernel,
  git clone -b devel
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git

 In u-boot
 git clone -b renesas/bsp/rcar-gen2-1.8.0  git://git.denx.de/u-boot-sh.git

 2) build
 In kernel,  I used kernel config file as "shmobile_defconfig" and
enable "DEBUG_LL"
 with cross-compiler
"gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf" ( cross_compiler
download site :
https://releases.linaro.org/15.02/components/toolchain/binaries/arm-linux-gnueabihf/gcc-linaro-4.9-2015.02-3-x86_64_arm-linux-gnueabihf.tar.xz)

 Build it  like below command and got zImage and dtb file(r8a7790-lager.dtb)

 $make ARH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j10

 In u-boot, I used config file as "lager_config" and build with
compiler used in kernel build like below. And then got "u-boot.srec"

 $ make ARH=arm lager_config
 $ make ARH=arm CROSS_COMPILE=arm-linux-gnueabihf- all

 3) Setting the environment for booting

 The environment have been loading kernel via TFTP and rootfs via NFS.
And U-boot command are set with below.

 > setenv bootcmd 'tftp 0x40007fc0 zImage; tftp 0x4f000000
r8a7790-lager.dtb; bootz 0x40007fc0 - 0x4f000000'
 > setenv bootargs 'console=ttySC6,38400 ignore_loglevel psci=enable
rw root=/dev/nfs rw nfsroot\x192.168.0.228:/nfsroot/lager,nfsvers=3
ip\x192.168.0.91:192.168.0.228:192.168.0.1:255.255.255.0:lager:eth0:::
vmalloc84M'


 4) power on "R-CAR LAGER Board"

 Lager board had hang before booting linux kernel with message "
Starting kernel ... " and "Uncompressing Linux... done, booting the
kernel."

 Anybody help me to bring up "Lager board"

 Thanks.

The console device should be ttySC0, not ttySC6.
Furthermore, is 38400 correct for your configuration? I'd expect 115200.

Note that with Simon's current tree, there should be no need to specify
a "console" parameter, unless you really want ttySC6 or 38400 baud.

What does "psci=enable" do?

Does the kernel boot with the default kernel command line?

You said you are using "CONFIG_DEBUG_LL=y". Are the other config
settings for early debugging correct?

CONFIG_DEBUG_RCAR_GEN2_SCIF0=y
CONFIG_DEBUG_LL_INCLUDE="debug/renesas-scif.S"
CONFIG_DEBUG_UART_PHYS=0xe6e60000

BTW, arch/arm/Kconfig.debug still assumes SCIF0 for debugging on r8a7790,
while the console uses SCIFA0 these days. However, changing that makes sense
only if U-Boot is also changed to uses SCIFA0, else pinctrl is not set up
correctly. Perhaps U-Boot has been changed, and that's why it doesn't work?

Re: [R-CAR][Lager Board - Bringup with linux kernel4.3]

[조창환]

Hello,

Thank you so much. I fixed with your advice.
I set console port as ttySC6 following with renesas's document about booting.
Anyway I got success booting and rootfs with NFS.
