Hi Lukasz,
Myself and Joris have been working on DM conversion of pico-mx7 and
the the latest patches are available at:
https://github.com/jorisoffouga/u-boot/commits/pico-imx7d/convert-dm
Things are working well so far, except eMMC flashing via DFU.
The following error is seen we flash u-boot-dtb.img:
=> dfu 0 mmc 0
Request would exceed designated area!
#Deferred dfu_flush() failed!=>
Joris found a way to fix this problem by doing:
#define CONFIG_DFU_ENV_SETTINGS \
"dfu_alt_info=" \
"spl raw 0x2 0x400;" \
- "u-boot raw 0x8a 0x400;" \
+ "u-boot raw 0x8a 0x1000;" \
"/boot/zImage ext4 0 1;" \
"/boot/imx7d-pico-hobbit.dtb ext4 0 1;" \
"/boot/imx7d-pico-pi.dtb ext4 0 1;" \
Is this an acceptable fix?
What does the last field in dfu_alt_info mean?
Thanks,
Fabio Estevam
