Flash memory 64mb:
I need to find a solution to connect a pcb with a cable though usb and after that, read and flash from chips soldered on. Right now I can read an flash software but I have to desoldering and sold back the chip / processor. I need to avoid this procedure using a cable and a program/interface. Also, on the pcb there is a SD card with a backup copy of the software inside the chip but I need a solution to flash from sd, maybe better way to flash a new software on the chip (avoid the usb cable?). Right now I can’t flash the newest software version in my possession because I don’t know the procedure to read and flash from SD.
