Hi all,
I recently bought a Gigabyte MZ32-AR0 Rev 1.0. I only have an epyc 7642, and when I installed in the board and powered up, I got no video both via VGA out or via the BMC. The board originally came with R20 BIOS, and an old BMC firmware (from 2020). After countless attempts, I managed to update the BMC to the latest firmware (12.61.21).
I then proceeded to update the BIOS to R28_F04 using image.rbu file. After also encountering " failed due to verification image fail" countless times, reflashing the BMC, and doing BMC a cold restart finally resulted in successfully flashing R28. However, the board still shows nothing and when I power it on, the LEDs near the ATX power connector all turn solid on, except the CPLD_LED which flashes slowly. I have rflashed the BIOS with R28_F04 a couple more times (successfully), but nothing has changed.
I have tried copying the BIOS image to a USB stick and power with that inserted in the motherboard's rear USB ports without success.
As you can see in the image below, when the Firmware Information page under Maintenance shows only the BMC version, no BIOS version, and the CPLD firmware version is unavailable.
As others have previously pointed, flashing the CPLD requires a RCU file, which Gigabyte doesn't provide for download.
What else can I do?
