maybe wire the spi to a SD card adaptor and put uboot on a bootable SD card?

Thank for the ideas guys.  Looks like I'll have to locate a socket and de-solder the flash chip after all.  I ran into lots of blocking due to design choices.  The chip's outputs aren't tristate, the JTAG pins are in use, the bootloader kills JTAG early, and there's no SWD support.  I'd guess the designer never wrote bad code, but I'm trying to fix the mess he made.  (lol)

So, I need to find a SPI Flash programer that will support a Winbond W25Q128.  Any suggestions?

Mike
