Description
The recovery procedure consists of following steps:
- Loading bootloader binary over JTAG interface using OpenOCD Programming feature
- Running bootloader from RAM
- Flashing bootloader over Ethernet
- Erasing bootloader environment
- Flashing kernel over Ethernet
- Flashing root filesystem over Ethernet
- Resetting module
Requirements:
- JTAG adapter with OpenOCD software
- Serial adapter with terminal application
- Running TFTP server
- Running DHCP server (optional)
Yocto Project
