Hi,
I am doing a job with nRF52832 with keil in initial period. I have two peripherals and connect to nRF52832 via uart, and it runs well. Recently, I migrate the job to gcc environment. All runs well except for the ble. My phone can't connect to device anymore, but it works with keil hex well. When remove the two uart peripherals, I can connect to device via ble.... But the code is identical between keil and gcc.
My sdk version is S132, sdk is 15.0.0 and phone tool is nRF connect. The softdevice(6.0.0) is programmed and app download nextly. And before compiling, I checked the ROM and RAM in .ld file:
MEMORY
{
FLASH (rx) : ORIGIN = 0x26000, LENGTH = 0x5a000
RAM (rwx) : ORIGIN = 0x20003000, LENGTH = 0xD000
}
So my question is : Is it different between keil and gcc when compiling ble (or uart)? or need to define macro i missed.
My part of makefile is below:
