FT232H over USB from linux computer used to program Olimex iCE40HX1K-EVB flash chip. First applied 5v power from USB to pin 1 and GND to pin 2 of the BH34R extension header. Then connected the first 4 pins of the FT232H's AD port to the olimex's UEXT header like:
| FT232H | Olimex UEXT |
|---|---|
| ADO (CLK) | 9 (iCE40-SCK) |
| AD1 (MOSI) | 8 (iCE40-SDO) |
| AD2 (MISO) | 7 (iCE40-SDI) |
| AD3 (CS) | 10 (iCE40-SS) |
Then after build the blinky test program, then before using FLASHROM I need to first expand the blinky.bin image from 32kB to be 2MB by using command:
truncate -s 2M blinky.bin
Note: I'm using flashrom because iceprog was giving me issues. I can now run flashrom directly:
flashrom -p ft2232_spi:type=232H -w blinky.bin
which produces this output:
flashrom v1.5.1 (git:v1.5.1) on Linux 6.13.4-arch1-1 (x86_64)
flashrom is free software, get the source code at https://flashrom.org
Found Eon flash chip "EN25QH16" (2048 kB, SPI) on ft2232_spi.

Thanks for your help!
Reading old flash chip contents... done.
Updating flash chip contents...
It seemed to have hung after that, but I pressed Ctrl-C and amazingly it would now run the blinky test.
