u-boot DDR3 Custom IMX6SLL

[vlintilhac]

Hello,

I'm trying to update u-boot for my custom board using a different LPDDR3 (W63CH2MBVACE - datasheet attached).

I have made the following changes but cannot get u-boot to show up in the console:

[x] u-boot/board/freescale/mx6sllevk/imximage.cfg -> updated with calibration values I got from the stress test

[x] u-boot/board/freescale/mx6sllevk/plugin.S -> updated with calibration values I got from the stress test

[x] u-boot/configs/mx6sllevk.defconfig -> CONFIG_NR_DRAM_BANKS=3 (my ram is a 8 banks DDR)

[x] u-boot/include/configs/mx6sllevk.h -> PHYS_SDRAM_SIZE    SZ_512M (512MB DDR)

Is there anything else I need to update to get u-boot to work properly? Or any tips to debug?

Best,

Vincent

Hi Vincent

for that issue one can try to decrease cma size and build without OPTee, using

sect.5.6.10 OP-TEE enablement    i.MX Yocto Project User’s Guide​

For debugging one can use AN4553   Using Open Source Debugging Tools for Linux on i.MX Processors
