Hello,
I have Samsung HD502IJ with totally damaged motherboard. I have new board with the same model and revision, but there is no small rom chip, instead of this, is Marwell 88i8826D-BAM2 processor.
1) Is there any option to connect to pins on motherboard and read rom from this chip, and program chip in new board?
2) Will it work, when I swap this BGA chip from broken board to new one?
Have a nice day!

Can you share pic of both PCBS and where damage is please? PCB number would be handy too.
Checking some sites, that Processor matches up with up some that have External ROM so it would be good to see the whole board.
What's up with the native patient PCB?
Does Donor PCB with Donor ROM spin up the drive?
Sometimes you can get lucky and it will work without a ROM swap, but I've mostly seen that on some M7 and M8 drives where just a PCB swap will work and the drive will initialise and read even with non native ROM.

1- Yes, normally there is, but only if the board works to a degree. If it's electronically faulty it might be possible to repair it. Depends on what's wrong with it. Photo of damaged PCB will help
2- If the ROM is not external and on the MCU, then yes, provided it is undamaged.
