Read_from_flash command not found

[Shadan]

The guide to configure FPGA from flash via SPI utilizes the read_from_flash command as mentioned in the link .

While doing so via terminal in PuTTY the following error is produced :

What do you want to do? Do you want to flash the bitstream on th FPGA?

To flash the bitstream,

sudo apt update
sudo apt install bitman
sudo bitman -f <bitstream_file>

Yeah i wanted to flash the bitstream and make it be non-volatile because vaaman -ctl is volatile right.
Sure I’ll try this.

[djkabutar]

It cannot be non-volatile as we are not copying the bitstream to flash anymore, we are programming it directly using spi passive mode.

You can create a service which will flash the bitstream on every reboot if you want.

Oh okay. Yeah that is what we are doing, but wanted try a non volatile method if possible. Thanks for the clarification.
