Other Parts Discussed in Thread: CSD
The SDK version I use is PROCESSOR-SDK-LINUX-AUTOMOTIVE 6_00_00_03.
Sometimes uboot will stop at the following position, but it will not stop here every time, sometimes it can start normally.
U-Boot SPL 2019.01 (May 12 2020 - 17:03:18 +0800)
Trying to boot from MMC2_2
no pinctrl state for default mode
spl: mmc init failed with error: -22
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
I locate the error code in the following file:uboot\drivers\mmc\mmc.c
In the following functions:mmc_startup_v4()
The following code in this function returns an error:
if(ext_csd[EXT_CSD_REV] >= ARRAY_SIZE(mmc_versions))
What is the meaning of this code and why there are errors here？
