Hi,
I am migrating U-boot 2016 to 2020 version for AM335x based custom board. I am facing issue in booting kernel from U-boot 2020 using autoboot commands. I am specifying the env boot commands in include/configs/am335x_evm.h file but while executing run loadbootenv command for loading our uEnv.txt file It was giving syntax error. Here I want to load uEnv.txt file from mmc1 and 2nd partition. The same commands working in U-boot 2016 version. I am posting the commands and as well as error logs. Please check and help me out in this...
"bootenv=uEnv.txt\0" \
"loadbootenv=" \
"echo reading uEnv.txt;" \
"echo --${mmcinterface}:${rootfspart}--;" \
"if load mmc 0:2 ${loadaddr} ${bootenv}; then" \
"echo uEnv.txt read fom uSD main partition;" \
"else " \
"if load mmc ${mmcinterface}:${rootfspart} ${loadaddr} ${bootenv}; then" \
"echo uEnv.txt read fom eMMC main partition;" \
"else" \
"echo uEnv.txt not found in active partition" \
"fi; " \
"fi;\0" \
"if run loadbootscript; then " \
"run bootscript;" \
"else " \
"if run loadbootenv; then" \
"echo Loaded environment from ${bootenv};" \
"run importbootenv;" \
"fi;" \
"if test -n $uenvcmd; then " \
"echo Running uenvcmd ...;" \
"run uenvcmd;" \
"fi;" \
"if run loadimage; then " \
"run mmcloados;" \
"fi;" \
"fi;\0" \
error logs:
