Well this is second time I need to reprogram an SPI aware device (first it was a serial Flash memory on a Xilinx board where device was JTAG aware but did not program this way, second it is a parallel Flash memory conncted to a BlueCore4 IC where IC can act as a SPI slave but have no JTAG), so the problem comes back somewhere near the JTAG aware devices. I have a memory programmer and I can implement a SPI on it, but I think it is possible to use a FT2232 device to toggle lines a bit in another way thank JTAG, so UrJTAG could also program SPI devices - this could make it pretty all-in-one tool, and the SPI is a bus itself, I will take a look at this :-) Best regards, Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info ------------------------------------------------------------------------------ _______________________________________________ UrJTAG-development mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/urjtag-development
