Uboot question for LS1046

michaelchen_nsb — Tue, 11 Jul 2017 02:11:25 GMT

hi, I have few questions about uboot for LS1046,

First question: I can't boot from Bank4, I use command "cpld reset altbank", probably the bank 4 is crashed, how can I recover it?

Second question, the bootcmd is abnormal, i use command

"setenv bootcmd sf probe 0:0;sf read $kernel_load $kernel_start $kernel_size;bootm $kernel_load"

to config the parameters, but, it boot immediatly that I am not possible to use saveenv to save the parameter, what should i do?

followed the the detailed printenv

Refer to the NXP Linux SDK Infocenter:

2) The "bootcmd" parameters should be quoted by ('):

setenv bootcmd 'sf probe 0:0;sf read $kernel_load $kernel_start $kernel_size;bootm $kernel_load'

Please confirm that the switches' settings are as described in the Infocenter.

The command sequence looks correct.
