Unable to program Zedboard [Error: Failed to claim FPGA device: Error: can't flash Zynq7000] about openfpgaloader

[trabucayre]

Hello,
As mentioned in this issue it's not an internal error but simply because SPI flash is connected to PS pins and can't be accessed from PL.
I have updated xilinx.cpp to have a more explicit message.

Thanks!

Please note that I'm not using the -f flag

Sorry. I have seen this error and immediately think about this issue.
Could you try with -b zedboard ?
I have retested and no issue, but I have used an Linux computer. It's weird because default behavior is volatile memory.

[gian-didom]

I think that the script itself tries to write to volatile memory, because a message appears when using -f instead.
I will try with a different cable. Do both JTAG and UART ports of the ZedBoard need to be connected?
I'll also try with a Linux computer.

I think I found why openFPGALoader try to write to the flash:
In your command line you have a bitstream called sampleProject.blt with BLT as extension instead of BIT.
If you check this couple of lines target choise is based on user information + extension: a .blt extension isn't a know bitstream file and considered as a raw binary data (can't be used for SRAM mode) to write somewhere into the flash.
