[U-Boot] Rockpro64_V2.1 2018-07-02 Boot Freeze

[U-Boot] Rockpro64_V2.1 2018-07-02 Boot Freeze

[Kurt Miller]

Hello,

The Rockpro64_V2.1 2018-07-02 using master code base freezes
with only the following output:

U-Boot TPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31)

Whereas another board dated 2018-06-06 works and outputs the following:

U-Boot TPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31)
Trying to boot from BOOTROM
Returning to boot ROM... 

U-Boot SPL 2019.10-rc2-00001-gdf33f86468-dirty (Aug 16 2019 - 22:31:31 +0200)

Both board have 4G RAM.

U-Boot was built by Mark Kettenis from master with only the
baud rate changed for both tests. The 2018-07-02 board has different
markings for the CPU and the RAM as follows:

     2018-06-06       2018-07-02
CPU: RK3399           RK3399
     SBETMF976 1652   SBETNM271 1826

RAM: PS006-075 BT     PS052-053 BT
     N1YJ             83RL

Please let me know if there is additional information needed to
further diagnose the boot freeze.

Regards,
-Kurt

Please use mainline, and with doc/README.rockchip instructions.

I'm able to boot with mainline tree.

This is mainline as of Aug 16.  I built the image for Kurt and it the
same binaries (one for TPL+SPL one for U-Boot+ATF) works fine on my
board.

> I'm able to boot with mainline tree.

Sure I can believe that.  I believe your board from the same batch as
mine.  I suspect that the DRAM used on Kurt's board may require
slightly different timings.

While my board (2018-07-02) freezes with Aug 16 mainline TPL,
it does boot ok with the rockchip-linux TPL with the following
output which may have some useful info:

It's possible to dump the register after training in mainline uboot?

I'm working on getting master to build now. How would I
go about dumping the register after training?

Yes, this can be the cause. Thanks for pointing this.

I think rockchip-linux doesn't have lddr4 code instead they rely on
ddr bin, you can use same bin in Mainline w/o enabling TPL it would
work like

rkbin => SPL => U-Boot proper

Okay.

There are two possible areas to look here.

1) sdram timings, like the one ie used via .dtsi
    Use the working ddr bin and identify the board working frequency
and follow below instructions to get the sdram dtsi
    https://wiki.amarulasolutions.com/found/target/rk3399_sdram.html

2) lpddr4 set rate sequence in driver, may not be a problem but only
if 1) failed
    right now, the driver would start initializing the actual board
frequency(50MHz on my board) and then it switches to 400MHz and 800MHz
simultaneously to make the proper sequence work on each channel with
associated training.

It would be a bit hard, I tried below sequence at the end of
sdram_init (sorry for direct copy)

        printf("cic: ctr10: (0x%x - 0x%x)\n", &dram->cic->cic_ctrl0,
readl(&dram->cic->cic_ctrl0));
        printf("cic: status0: (0x%x - 0x%x)\n",
&dram->cic->cic_status0, readl(&dram->cic->cic_status0));
        printf("grf: ddrc0_con0 (0x%x - 0x%x)\n",
&dram->grf->ddrc0_con0, readl(&dram->grf->ddrc0_con0));
        printf("grf: ddrc1_con0 (0x%x - 0x%x)\n",
&dram->grf->ddrc1_con0, readl(&dram->grf->ddrc1_con0));
        printf("grf: soc_con0 (0x%x - 0x%x)\n", &dram->grf->soc_con0,
readl(&dram->grf->soc_con0));
        printf("pmu: noc_auto_ena (0x%x - 0x%x)\n",
&dram->pmu->pmu_noc_auto_ena, readl(&dram->pmu->pmu_noc_auto_ena));
        printf("pmu: bus_idle_req (0x%x - 0x%x)\n",
&dram->pmu->pmu_bus_idle_req, readl(&dram->pmu->pmu_bus_idle_req));
        printf("pmu: bus_idle_st (0x%x - 0x%x)\n",
&dram->pmu->pmu_bus_idle_st, readl(&dram->pmu->pmu_bus_idle_st));
        printf("pmugrf: os_reg2 (0x%x - 0x%x)\n",
&dram->pmugrf->os_reg2, readl(&dram->pmugrf->os_reg2));
        printf("pmugrf: os_reg3 (0x%x - 0x%x)\n",
&dram->pmugrf->os_reg3, readl(&dram->pmugrf->os_reg3));
        printf("pmusgrf: soc_con4 (0x%x - 0x%x)\n",

Thank you. I have built mainline with CONFIG_RAM_ROCKCHIP_DEBUG=y

I see 'Size=2048MB'.

Is your board running at 50MHz? (look like No). As I said please
explore step-by-step
00: First boot the board rkbin => SPL => U-Boot proper
01: Grab the sdram-*.dtsi (steps mentioned in previous mail) and
replace rkbin withTPL
02: Then dump the regmap if 01 failed.

Thank you. In the above output I saw this:

change freq to 856MHz 1,0

There is one entry in rk3399pro_ddr_800MHz_v1.23.bin for 856Mhz and
I was able to extract the DDR timings through step 4 in the provided
link. However from there the instructions don't appear to be correct
and I'm unsure how to get the timings formatted (step 5 and 6) and
added into the build.

Could you provide some additional guidance with these steps?

No it is running at 800Mhz or 856MHz (see rkbin TPL output below).

This step was completed already. Here is the output again for reference:

I am stuck here. I see that there were three 800Mhz entries
in the rkbin rk3399_ddr_800MHz_v1.20.bin file that was used to
create ./arch/arm/dts/rk3399-sdram-lpddr4-100.dtsi.

rk3399-sdram-lpddr4-100.dtsi has one entry that appears to
be from the first 800Mhz data in rk3399_ddr_800MHz_v1.20.bin.

Using the instructions you linked:
https://wiki.amarulasolutions.com/found/target/rk3399_sdram.html

I have inspected rkbin rk3399_ddr_800MHz_v1.23.bin and found
there are two 800Mhz entries in it. I have extracted the two
entries but have have questions that the instructions don't
address well.

Why does the existing rk3399-sdram-lpddr4-100.dtsi only have
one entry while the instructions appear to indicate there
should be two, one for single and another for dual ranked?

Step 6 refers to editing the dtsi file:

"..., edit the initial values (don’t forget that they are in
little endian form) to match what the SPL code expects, 
convert the frequency value from the binary back into MHz
(line 38 in the attached dtsi files for reference)"

I believe I was able to convert the data into the updated
values correctly (see attached diff). However, one value
stood out to me. The 800Mhz value of 0x2faf0800 was converted
into decimal 50 in the existing data whereas other sdram files
converted it into 1/2 the Mhz value (e.g. 800Mhz -> 400).

With it set to 50 I get this output before it stops:

U-Boot TPL 2019.10-rc2-00016-g81fed78c0a-dirty (Aug 19 2019 - 18:45:16)         
pctl_start: Failed to init pctl for channel 0 

With it set to 400 I get this output before it stops:

01 failed. With the timings diff reverted I get this before it freezes:

Yes! It fixes my boot issue. Thank you for working on it.

However there is a second issue. Only 2G of memory was recognized
instead of the 4G the board has. I added this to get more
debug output:
