I'm using an imx8mqevk dev board and I'm booting using the micro SD. I've configured the build to include u-boot-fw-utils in the image as described here:
https://community.nxp.com/t5/P-Series/How-do-I-get-fw-printenv-and-fw-setenv-included-in-my-rootfs/m...
However, I'm having trouble identifying valid settings for the /etc/fw_env.conf. I've identified that uboot-imx uses the following values in imx8mq_evk.h:
https://source.codeaurora.org/external/imx/uboot-imx/tree/include/configs/imx8mq_evk.h?h=lf-5.4.y_v2...
#define CONFIG_ENV_OVERWRITE
#define CONFIG_ENV_OFFSET (64 * SZ_64K)
#define CONFIG_ENV_SIZE 0x1000
#define CONFIG_SYS_MMC_ENV_DEV 1 /* USDHC2 */
#define CONFIG_MMCROOT "/dev/mmcblk1p2" /* USDHC2 */
I assumed that if this were correct, my valid settings should be
# MTD device name Device offset Env. size Flash sector size
/dev/mmcblk1 0x400000 0x1000
or perhaps /dev/mmcblk1p1. However, using either of these options gives me the same result:
root@imx8mqevk:~#fw_printenv
Cannot read environment, using default
Cannot read default environment from file
Do you know where I can find a valid fw_env.conf for this board?
Thanks,
Martin Dillon
