You might need to desolder the flash chip, if you can't figure out how to hold the CPU in reset. It looks like the c7 has a regular SPI flash chip. It is probably just an 8-pin part, and not too hard to desolder, if you need to. Solder wick is handy for cleaning up the pads after you remove it. I have recently used a bus pirate or a teensy 3.1 with the flashrom program to read/write spi flash. Likely to be Way easier that trying to figure out JTAG. Make *very* sure you have a (or several) complete backup of the flash part before writing over it. -- Russell Senior, President [email protected] _______________________________________________ Lede-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/lede-dev
