Error while using CC2520 SPI peripheral on STM32F4

[dtd131001]

I want to ask about using CC2520 SPI peripheral on STM32F4 to simulate a custom board. I followed the Quark C1000 - CC2520 and added the SPI to the .repl, but when I try to run a binary I get: "Direct access to txFifo is not supported. Trying to access 0x..." and "Failed to write to register".


I really appreciate any help.
