Hello, Target MCU is NXP LPC55S06JBD64IntroductionI wanted to test the sample "lora_send" using the shield SX1261MB1BAS. Testing LoRa sample with board Lpcxpresso55s69Zephyr has working implementation of HS SPI bus for NXP Lpcxpresso55s69. The target board: Lpcxpresso55s06Zephyr supports this board but the features enabled are reduced. What I tried:I tried to enable the SPI bus following the configs files of Lpcxpresso55s69. With a logic analyzer I tested the pins MOSI and SCK of Lpcxpresso55s06 but they are disabled. sx126x Zephyr driver doesn't report any SPI bus error.
so, SPI bus looks like is not working at all. Can you please review my work and files below to see if I need to add or modify something? Thank you so much everybody. command to build:

Hello, I discovered the can bus use the same SPI bus of the Arduino header on the lpcxpresso55s06 board. Also the JP9 has to be installed to isolate the SPI signals coming from the ISP companion MCU. The sample finnaly works onto the target board and MCU. Thank you and sorry for the noise. F. |
