Please help me.Thank you!

Hi  talent liu

usually wake errors are not related to ddr settings, but

wrong bsp. Please try with some of i.MX6SL nxp bsps described on

https://www.nxp.com/support/developer-resources/run-time-software/i.mx-developer-resources/i.mx-6ser...

First run ddr test

i.MX6/7 DDR Stress Test Tool V2.80 

then rebuild image with new calibration coefficients found from ddr test, update them in

uboot/../mx6slevk/imximage.cfg

Best regards
igor

Hi igorpadykov

Both DDR stress tests and memtester can be passed.I use the android4.4.2 bsp.

It is normal to wake up with 2GB of memory on the same machine.

[igorpadykov]

suggest to check wake functionality with Linux BSP L3.0.35 (used in android4.4.2) in

minimal configuration.

Best regards
igor

The hardware is replaced with 2gb of lpddr2 burning 2gb uboot, boot. Img is unchanged, and it wakes up normally.

With 1GB of LPDDR2 and 1GB of uboot, boot. Img invariant, the wake up failed.

In the experiment, the boot. Img and system. Img are the same.

Why use 1GB of lpaddr2 to wake up failure?
