u-boot relocate text base

xianwu_luo — Mon, 01 Apr 2019 18:29:23 GMT

Current u-boot is running in RAM at 0x4020,0000 . it is defined by

#define CONFIG_SYS_TEXT_BASE 0x40200000

I try to relocate it to 0x6020,0000 by change

#define CONFIG_SYS_TEXT_BASE 0x60200000

Use uuu to burn image to flash, seems it does not work.

it refused to write to flash

this is such a simple change. what could I missed?

thanks

Xian

Hi Xian

one can try to run uuu in shell mode : uuu -s .
Then one can input commands and run them at a shell prompt.

What is about burning image to flash without modifications, just recompiling it.

Please try uboot from source.codeaurora.org/external/imx repository

uboot-imx - i.MX U-Boot

what uboot (link) and processor used in the case.

One can consider Table 49. Board-specific default values in attached Linux Guide.
