Error writing to flash #268

Closed Onicc closed 1 year ago

Onicc commented 1 year ago

Hi,

I write bitstream to RAM everything works fine, but write to flash I get an error.

$ openFPGALoader -c ft232 -b zybo_z7_20 -f led_twinkle.bit
write to flash
Board default cable overridden with ft232
Jtag frequency : requested 6.00MHz   -> real 6.00MHz

As mentionned in the documentation write to flash is not available through JTAG. The SPI Flash is connected to the PS part and can't be acceded from FPGA. I'm agree the error is not explicit for this specific case and a check must be done at CTOR level with a better error message.

with commit openFPGALoader will no more tried wrongly to write bitstream for xc7z devices.

It's good to you? can I close it?

Yes, it's safe to close this issue, added error messages are more appropriate.
