As Roger said, if your radio returns REV: 0x9 then it will not at the moment work with OpenGD77.

None of the developers has one of these radios, so it is almost impossible to develop a fix.


Just for completeness My RT3S returns REV: 0x100F which is different to Rogers but still works OK.
My MD390 returns REV: 0x1007 which is the same as Rogers.

Can anyone who has the problem of the firmware not running on their new RT-3S / UV380 please try loading this test firmware

All it should do is flash the green LED several times a second.

This version only initialises the CPU click PLL and the GPIO pins and then flashes the LED using a delay loop, i.e its almost the bare minimum possible code.

i.e all it does is

Code: Select all

  HAL_Init();

 __HAL_RCC_SYSCLK_CONFIG(RCC_CFGR_SWS_HSI);

  SystemClock_Config();

  MX_GPIO_Init();

  while(true)
  {
	  HAL_GPIO_TogglePin(LED_GREEN_GPIO_Port, LED_GREEN_Pin);
	  for(volatile int i=0;i<1000000;i++);
  }

What seems to crash is the call to start FreeRTOS
