I would really appreciate if you guys explain how to build correctly the "SPI-only" firmware.

@mantriyogesh could you explain, please, how I can rebuild the "SPI-only" firmware to allow the raw throughput test ?

@mantriyogesh I verified both irq handlers by adding simple logs, they both appear to work correctly Changing SPI clock doesn't do any effect on my system, the error persists.
