Fails to boot up device with 4GB LPDDR on iMX8QXP-B0 under eMMC boot mode, however uuu flashing is ok under serial mode

[leon_uan]

Hi,

My customized images can be flashed into device via uuu tool, and its logs seems normal, see attached logs (uart log and uuu tool log). But device cannot bring up after changing boot switch to eMMC boot mode

Do you have any suggestion?

#1
I pass DDR test using mx8_ddr_tool_ER8, and its ddr test logs
One-time test log: test_result_20190527-13'9'18.log
Overnight test log: test_result_20190531-9'7'37.log
DDR Test script: mx8qxb0_lpddr4_1200mhz_RPAv11_fs8700_1024Gb_MT53D1024M32D4.ds

#2
Device boot up fail in emmc mode no matter ddr cfg file is generated based on v11 or v9 MX8QXP_LPDDR4_register_programming_aid excel file

#3
I also tried the following settings, but device still fail to boot up
#changed size (memory@80000000) in uboot/linux dts to 2GB
#changed PHYS_SDRAM_2_SIZE to 2GB

My SCFW build cmd is:
make clean
make clean-qx
make qx B=mek R=B0 D=1 DL=5 M=0 Z=fs8700_1024Gb DDR_CON=ddr_stress_test_parser
mv build_mx8qx_b0/scfw_tcm.bin build_mx8qx_b0/scfw_tcm_fs8700_1024Gb_ddrtest

make clean
make clean-qx
make qx B=mek R=B0 D=1 DL=5 M=0 Z=fs8700_1024Gb
# "Z=fs8700_1024Gb" is my compile option for including MT53D1024M32D4 cfg file

Hi Igor,

I am waiting for factory to replace/rework 4GB LPDDR4 by 3GB one

However, we find ... it seems that flash.bin can't be flashed into eMMC properly by the following command
FB: flash bootloader flash.bin (uuu_xxx.uuu)

If I execute 2 more following commands before flashing rootfs.sdcard and flash.bin (uuu_xxx.auto), device can partially boot up after changing boot mode to eMMC
FB: ucmd mmc dev 0 1
FB: ucmd mmc partconf 0 1 7 0

Do you have any suggestion?

Hi Leon

one can try to flash emmc image without uuu, please use Linux User Guide from documentation

Linux L4.14.98_2.0.0 Documentation

Hi Igor,

I rebuild image with the following configs, but device still can not boot up...

Do I need to revise more ATF or SCFW or M4 or ...etc. code if changing LPDDR4 size to 4GB?

Or any more suggestion?

Hi Leon

is it booting fine with 2/3GB?

Best regards
igor

[igorpadykov]

Hi Leon

may be recommended to rebuild image with latest configs

derived from mx8_ddr_stress_test_ER9 and using RPA tool v12.

Latest SCFW v.1.2.1 can be found on

i.MX Software | NXP 

Use latest Linux L4.14.98_2.0.0
linux-imx - i.MX Linux kernel

I following the user guides and employ the below tools for imx8qm mek board:

   1.SCFW source: imx-scfw-porting-kit-1.3.3

   2.DDR stress test tool: mx8_ddr_stress_test_ER14

   3.DDR Register Programming Aid(RPA): MX8QM_B0_LPDDR4_RPA_1.6GHz_v21.xlsx

Then I  try to make SCFW with ddr_stress_test_parser config, but get this error. 

Please tell me where I can get this "DRAM_VREF_training_sw()"? thanks.

  $ make SOC=MX8QM qm B=mek R=B0 DDR_CON=ddr_stress_test_parser

By now, following errors always coming out on my iMX8QM board, how to fix it? or any patch for kernel v 4.19.35? Thanks in advance.
