Reading the firmware takes a while. If I remember correctly it took more than half an hour to write the firmware.
Arduino Nano should work, though I have not tried with this particular Arduino Board. I have used Arduino Mini Pro.
there’s a little dot on the corner of the chip, align it with the red cable on the clamp. By the way.. you can’t flash the chip with the SPHOST.BRN file, you have to use the original .BIN file from the working chip.
contact me at dfebrihardy6@yahoo.com if you want the original firmware.
]]>Hi Agnus, can u show all pins to connected with clamp? and send the model of the programmer that you use?
Thanks
Hi Agnus, can u show all pins to connected with clamp? Thanks
]]>Hi, well at the time of writing this article I was not aware about the CH341A programmer. Also the idea of using simple Arduino board was fascinating me.
Thanks for the info.
Try to flash the firmware with Arduino/Flashrom as described in the article.
