Description
The recovery procedure consists of following steps:
- Downloading binaries from Voipac download webpage
- Flashing binaries and filesystem over Baseboard USB-C connector
- Setting a suitable dtb file in bootloader (u-boot)
- Resetting and booting a module
Recommended Software
- Universal Update Utility (UUU)
- Windows Command Promt
- TFTP Server
- DHCP Server (Otional)
Configuration
Updating U-boot and Filesystem
Download u-boot file:
Download filesystem:
https://downloads.voipac.com/index.php?p=iMX8M_Industrial_Development_Kit/module/software/filesystem
Download Universal Update Utility (UUU) if needed:
https://github.com/nxp-imx/mfgtools/releases
Create a new folder e.g. C:\uuu and move all downloaded files into it.
Flashing uboot and filesystem
Prepare Voipac baseboard and follow the steps to flash the module as shown on this page.
Setting a suitable dtb file in bootloader (u-boot)
Stop autoboot in bootloader:
