I have two Tang Nano boards both give the same error when trying to flash. As it's terrible to get them working on Windows with "official" tools I really hope to get openFPGALoader to work. The output…

I've CRC error when I try to write the flash of the FPGA.
I succeed to write the SRAM without any problem and the code is running.

Hi,
Thank you very much for your library. I see you said this library supports "Nano 33 BLE OTA over TCP should work too (I have nRF5 support in the library)". I am using Nano 33 BLE which has no W…

Hi,
The recommended reference FPGA board is quite expensive. Are there any cheap FPGAs (such as ecp5, ice40, Tang nano, …) known to work with Opentitan?
I will appreciate any assistance.
