Hi, I try to update emmc rootfs, kernel and dtb using dhcp on ethernet link from uboot.
Uboot version is preloaded by toradex in the colibri board (U-Boot 2019.07-3.0.4+g26d926eda0). It seems that mbr is broken on emmc (during manual update rootfs on linux).
I get the following message No partition table - mmc 0
When i check with gpt utils :
Colibri iMX7 # gpt guid mmc 0 GUID Partition Table Header signature is wrong: 0x0 != 0x545... get_disk_guid: ERROR: Invalid GPT GUID Partition Table Header signature is wrong: 0x0 != 0x545.. get_disk_guid: ERROR: Invalid Backup GPT error!
With mmc cmd :
mmc hwpartition Partition configuration: No enhanced user data area No GP1 partition No GP2 partition No GP3 partition No GP4 partition Card already partitioned Failed!
How could I recreate the partition table from uboot ? How could I reload the tezi img when i’m blocked in uboot ?
In uboot, USB seems not working i check with many memory keys (fat32,ntfs, vfat), and i get the following message:
scanning bus usb@30b10000 for devices... 1 USB Device(s) found scanning bus usb@30b20000 for devices... 1 USB Device(s) found scanning usb for storage devices... 0 Storage Device(s) found
Why the storage device is not found (for otg and host port of the colibri) ?
Thks,
