imx7ulp RAM error

kayiyeh — Thu, 21 Nov 2019 06:56:55 GMT

Hi there,

I used my imx7ulpevk and replaced the DRAM to a new 4Gb LPDDR3. After changing some code, I can bootup Linux and run "memtester" for DRAM burn in. Then I Run into an error. The error message is kind of lengthy and messy, please refer to the attached file and give some comments for direction of debug.

Regards,

Ka-Yi Yeh

Hi Ka-Yi

memtester errors description can be found on

Micromat :: Topic: Memory test failing solid bits (1/1)

ram - What can I do with the output of memtester when it shows bad memory? - Unix & Linux Stack Exchange

For new memory it is necessary to run ddr test i.MX6/7 DDR Stress Test Tool V3.00

and update ddr settings found from test in uboot

imximage.cfg\mx7ulp_evk\freescale\board - uboot-imx - i.MX U-Boot

Best regards
igor
