I have bricked a carambola2(module with board), I have another one too which is working. I have tried to use with a FT232H chip to dump flash contents from the working chip and burn to the bricked one. It doesn't seem to be working, so I cannot even extract the flash contents right now.
Can someone from 8devices staff give me the flash contents, and suggest a way to write to flash please?

@tty can you give me a working flash image, to get an image I would have to desolder the carambola I am working with too? Or is it available somewhere?

Easiest way to copy original u-boot from working device is:
cat /dev/mtd0 > /tmp/uboot_c2.bin
cat /dev/mtd1 > /tmp/uboot_env_c2.bin
Otherwise here you are links:
- uboot
- uboot enviroment.
