Hello everyone.

I have been using a FreHD on my TRS80/4 for months without any problem.

I've been using a FreHD on my TRS80/4 for months, without any problem. Two days ago, when the TRS was booting, the two leds of the FreHD lit up at the same time, the FreHD was no longer recognized.
According to the knowledge base, it would have been switched to bootloader.
On reboot, the green led blinked once, and still no boot.

I used the "m4-frehd-boot" image on my gotek to launch the FreHD, and on launch, it displays "Loading FREHD ROM. LOVE, -TJBCHRIS...", then black screen.

Changed the SD, with the same result, the PIC is still to blame.

Is it possible to test or reprogram the PIC through the serial port of the card?


I spent so much time looking for and getting my TRS, I'm sad I can't use it with the FreHD.

Thanks to all.

Olivier
