In this link: (stepes 1 to 5) I used the mfgtool2-brillo-mx7d-multa-emmc-firmware script instead of the mfgtool2-brillo-mx7d-pico-emmc-firmware script. The mfgtool2-brillo-mx7d-multa-emmc-firmware script have a command ""eMMC-Brillo-uboot-fuse"" (look pic below...


I bricked my device because this part of the ""eMMC-Brillo-uboot-fuse"" option/script in ucl2.xml


<CMD state="Updater" type="push" body="$ ls /sys/fsl_otp ">Showing HW_OCOTP fuse bank</CMD>
<CMD state="Updater" type="push" body="$ echo 0x10002810 > /sys/fsl_otp/HW_OCOTP_BOOT_CFG0">write 0x11204154 to /sys/fsl_otp/HW_OCOTP_BOOT_CFG0 fuse bank</CMD>
<CMD state="Updater" type="push" body="$ cat /sys/fsl_otp/HW_OCOTP_BOOT_CFG0 ">Read value from HW_OCOTP_CFG1 fuse bank</CMD>


My questions is: 


1) If I change the SOM application processor NXP i.MX7 ARM Cortex-A7+M4 (by this:… ) I will solved my issue?


2) Is there any way to fix the issue without changing SOM application processor NXP i.MX7 ARM Cortex-A7+M4?


3)  What kind of bga solder of the NXP i.MX7 ARM Cortex-A7+M4 in SOM pico-imx7d?




Can anyone help me
