Hi,

 

In this link: https://community.nxp.com/thread/452013 (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: https://br.mouser.com/ProductDetail/NXP-Semiconductors/MCIMX7D5EVM10SD?qs=sGAEpiMZZMve4%2FbfQkoj%252BGDWKQm1eQirvf6dcx9h… ) 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?

(BGA-488/BGA-541/lfbga-541/mapbga-488/tpbga-488)

?

 

Can anyone help me
