You chose the wrong bios chip. The 5744 has a 4MB bios.

He's trying to flash the EC SPI ROM, which is a 1Mb chip.

Yes thats right i already did the 4 mb chip that went okay but the ec chip doesnt want to be writen i did a read and back up but when i wanne write it it give the error

Yes my mistake ,"flash ec bios" . It seems the chip faulty and needs replacing with a new one.

Yeh agree with smdflea. If 4mb bios writes perfectly then nothing is wrong-so has to be ec bios chip itself

mostly it is badly soldered contact on ic or chip is 1.8V

Re: EC bios flash error with CH341A

Thats right.If the chip pins are not soldered properly onto the programmer you will be getting this error.
