After reading forum , and service manual from motherboard Air A1534 i trace Pinout to my programer. I can read full dump but no write.
Im using cheap programer CH341. When i try to erase or write i have "The chip and contents are in disagreement."
I have select windbon W25Q64BV but if i try to audetect chip type. Programer detect MXIC - MX25L6405D but cannot write.
I don´t have desoldering BGA i try to program via pads pin out.
Any suggestion or int to point me to problem.
Thanks
best regards
it's mean that the readed dump or the edited one is not exactly same size as chip internal memory.
it should be exactly same bytes available in EEPROM memory.
actually im having problems erasing chip and writing back to it and before i start messing with it i wanted to just check to make sure my checksum matched one of a clean one so if u wouldnt mind just posting checksum of a clean if available id appreciate it.
thanks
I know how to use Hex editor to remove password after $SVS, I need checksum from dump to determine if i have read correctly before I erase and attempt to write. thanks
imo if you do that, a clean GOOD dump will not have the same checksum, you need to remove the $SVS & the password that follows it.

well i read it a bunch of times, and checksum matches, and ive now wrote it a bunch of times and re-read it and compared that file a bunch of times and checksum matches but doesn't boot and from my limited experience is an indication that somethings wrong i have the 1.1 core m .
My storey... My model have a Macronix. Mini pro not support read or write. Sofi 8 Sofi 16 support read.... Cannot find a state to write. But now is total dead. Destroyer kill The Machine... Possible Macronix. New IC for this model, is very expensive for now. So i go to try to change by other Macronix. After test i back
