I-CUBE-LRWAN don't work on custom board: PHY txTimeOut ERROR

[SHATE.1]

Hello

i made a customised board using the STM32L476RETx mcu with a lora module : DORJI DRF1262T

I opened the project from i-cube-lrwan expansion package with the name SX1262dvk1das USING THE SX1262 AT 868MHz.

i updated the PINOUT of my MCU and exclude all unnecessary driver and board sensor not used.

when i compile, everything is OK with error and warnings

i program my board. the program run but in 4s112ms the program is bloqued and the message in the UART of " 4s112 ms PHY txTimeOut " is printed and everything is stopped.

SPI pin and CS and DIO1 are well connected and in the beginningof the run, i see a signal on this protocole. the board well worked in ping pong mode with another board

Please help

Thank you
