I've modified the firmware, but as always, be very careful with this procedure:Hi,@CaseySJ
I am very happy that you have not forgotten me.
Yes, I have plugged in the DP-IN port of the motherboard. If SSDT is not used, everything is normal, but there is no Thunderbolt Bus.
I have a CH341a programmer, it would be great if you could help me modify the firmware, thank you very much, this firmware can be used, I don’t know why it is only 288KB, my GC-AR V2 AIC firmware is also less than 1MB, please Fill the remaining space with 0xFF.
There is also a problem. When using SSDT, if it is a hot restart, nothing will be loaded under BR1B. Thunderbolt cannot be used, only cold boot can be loaded.
Thank you again for your help！
- Use an external SPI ROM reader/writer to read existing firmware at least 3 times and make sure (a) the contents are not empty and (b) the checksums are the same.
- Then flash the attached file, but keep the original one safe. It may well be necessary to flash original one back.
- If you're not careful, you might dislodge some surface-mount components near the firmware chip.
