Hi Carl, David
The launchpad CC3200 have FTDI 2232D for programming CC3200 MCU. I wanted
to use this FT2232 with flashrom.
I can finally use flashrom with launchpad cc3200.
But i have questions about ft2232_spi.c file (attached) in line 488
"buf[i++] = 0 & ~cs_bits; /* assertive */"
Why sets all pins to low state? I need keep one pin to high state.The
launchpad CC3200 requires keep Bit 7 to high state for work.
It work replacement line 488 for this buf[i++] = 0x80;
Any solution?
attach img with flashrom running. Sorry for quality
