Hi,

I have a board here with missing U2890.

Basically my mistake, Was replacing the USB-C ports and somehow, it went flying into the abyss of my Solder filtration filter.

Anyway, I'm not get PP1V1_UPC_XB_BMC, since I don't know if my donor board has a good ROM chip.

Has anybody made a backup of this TBT ROM for a 820-00840-A they could share ?
I have attached ROM of U2890 I got off another Donor, but I'm not sure if this is compete as I'm still stuck on 5V

Thanks

ok, since it looks like no one has taken dumps of the various TBT ROMS,

Here is WORKING one from board 820-00840 with C00 CD32s. I'll update B03 CD32s shortly.

I guess it's a good opportunity to upload these too…

I was finally able to get a 820-00281 donor board to try the U2890 TBT flash. I've attached that here
