LoRaWAN end node issue in dual core and single core project with CubeIDE

[CandraSN]

Hi I'm using Nucleo-WL55JC1 STM32WL development board for LoRaWAN end node dual core and i have a custom board with MCU STM32WLE5CBU6 for LoRaWAN end node single core.

I have configured LoRaWAN end node protocol parameters like this documentation (https://www.st.com/resource/en/application_note/dm00660451-how-to-build-a-lora-application-with-stm32cubewl-stmicroelectronics.pdf).

The program from the example project has been uploaded successfully. After I uploaded the LoRaWAN end node program to the STM32WL55JC1 (dual core) development board, it said "WARNING: There is a difference between the MAPPING_TABLE placement in memory: 0x20008000 and the address calculated according to the IPCCDBA option byte: 0x2003FFF0 The execution enters now in a while(1){} please check the CM4\MbMux\mbmuxif_sys.c or update the scatter file" on the external terminal via serial usb and couldn't send data to the server / gateway with OTAA. I have followed the solution steps given from this topic: (https://community.st.com/s/question/0D53W00000VgqmvSAB/trouble-with-the-stm32cubewl-dual-core-example-projects) and I still have problems like that

Meanwhile, for the single core STM32WLE5CBU6 MCU end node, the program was successfully uploaded with the Lora protocol configured. But there is no response / action from the node sending data to the server / gateway with OTAA. On this board, I'm not using TCXO and DCDC.

So, from the problem I got, is there a solution or configuration that I missed so that the nodes can send data with OTAA to the server / gateway with dual core or single core. I really appreciate your attention, thank you.

Hi @ASELSTM

Maybe i want to add something So, I have tried using Firmware Package v.0.4.0 + EWARM (IAR) toolchain and the result is that I can transmit data in OTAA and ABP modes with end node single core program. But, by using Firmware Package v.1.0.0 + cubeIDE toolchain with single core mcu, I have not succeeded in using it for data transmission to the gateway. I've configured it based on the following documentation (https://www.st.com/resource/en/application_note/dm00660451-how-to-build-a-lora-application-with-stm32cubewl-stmicroelectronics.pdf). After I uploaded the single core end node program to my custom board (STM32WLE5CBU6), there was no response from the board or gateway.

I focus on development with a single core STM32WL with this firmware package.

I'm really looking forward for your reply, thank you.
