Is it possible to Use chipmunk clip on a1534 EMC 2991?

Hi
If you look on Ebay they selling them and I used one of them unfortunately at this moment I forgot the model # but I did copy and edit and write it back ,works good

 

[dam1inc]

thank you, i CH1341A and chipmunk easy flash but always get errors writing..i also have sofi-sp8 but havent figured out how to connect easy flash to sofi-sp8. do you know how? I saw a post that said you use sofi-sp8 to read and write, for me the only way to read/write is to desolder the chip but its a super time killer

Yes please that would be great , I have CH1341A , easy flash adapter and also sofi-sp8
This model reads with ch1341a as micronix but it's windbond? I am able to read but erasing and writing not. Always give error as in screen shot, I used .bin from here and clear Region ME and still same thing[emoji20]

Hi first you must chose ISP from device like 25q64v (ISP) and hook up chipmunk wire this port

Normally I plug the power supply for the mac in and make sure has the power but computer is off after that I plug in the chipmunk on the socket and try to read after edit and writing on it make sure the chipmunk in the right direction
