external flasher for RE-UP-CHT01-A10-0116

coreboot

we are planning to set up a class on linuxboot at the next OCP summit in March. The UP board is a near-perfect board, but we need the ability to reflash from an external programmer. There is a mention of this in the manual but I'm not sure which connector/pins are the right ones to use, and, further, what voltage is needed. Finally, are there schematics anywhere?

Thanks.

Can you please confirm that you need it for UP Board?
I am moving the topic to the right section.

It was already done with UP Squared but for BIOS programming the pinout is different from UP Board.

To reflash the BIOS on UP Board from an external programmer, you would need to remove the back plate and use a clip with dediprog sf100:

@coreboot The voltage needed for programming the SPI flash is 1.8V

Is there a way to flash the UP Extreme (Celeron) using a dediprog ?
