I want to change the U-Boot environment variable (specifically only “bootdelay”) without using uart connected to serial console. I have looked at the forum and found “u-boot-tools” package. From what I’ve seen, people can change the variable by using fw_setenv. In order to use fw_setenv, /etc/fw_env.config file must be set correctly. What is the content of this file should be? Someone posted his config file (https://devtalk.nvidia.com/default/topic/1037561/jetson-tx2/fw_printenv-and-fw_setenv-in-tx2/post/5272612/#5272612)
/dev/mmcblk0boot1 0x3FE000 0x2000
But this one still gives me the following error and shows the default uboot variables:
Warning: Bad CRC, using default environment
This will be the first time I am going to change the uboot variable after flashing. Can I do this without using serial console?
Thanks in advance.
