[time-nuts] Samsung GCRU-D app image

[Mark Stephens VK2HMC]

I recently obtained a Samsung GCRU-D.

While trying to discover some commands with the serial port I erased the flash.

The flash is stored on a socketed 29F040 flash chip.

Designated U50; the flash is in a PLCC package.

I have 2 ways of recovering my only reference.

The first is reflash the chip with a binary image.

The second is upload the hex image through the serial port.

If you have one of these units, please help me out?


Best regards,
Mark
