It takes some practice to eventually get a feel for when a good clip happens. Be patient by resting the clipper flush on the mainboard first then slowly align the metal contacts to the chipset. The kernel device tree needs to specify the EEPROM's type and address, and which IC bus it's connected to.
The most crucial step is the clipper placement onto the EEPROM contact points. Alternatively, you could access it via the kernel at24.c driver, if you're able to compile and install a different kernel device tree for your Raspberry Pi. Together PROG and CPROG are useful for development, production line programming, or field firmware upgrades. Here are the components this EEPROM Flash Bios USB Programmer comes with. PROGCFZ also includes the command-line version of the programmer software, called CPROGCFZ, which allows scripted programming. The programming software includes P&E's entire library of ColdFire V2, V3 and V4 programming algorithms, and new algorithms are available free of charge. The interface connects the USB port of your PC to a 26-pin debug connector on the target system. Compatible Multilink interfaces for ColdFire V2, V3 and V4 development include the Multilink Universal and the high-speed Multilink Universal FX. This allows you to program/reprogram external ColdFire V2, V3 and V4 flash devices, in-circuit. P&E's PROGCFZ is Windows ®-based flash programming software for ColdFire ® V2, V3 and V4 MCUs that communicates with the processor's debug mode using a P&E Multilink hardware interface.
