I should have explained this in a bit more detail before. Sorry about that.
The code is crashing on the nrf51 because it is attempting to initialize too
many gpio irqs. The issue with the code is that it can support both FSK modes
and lora modes. Two of those interrupts are not used for lora and you do not
have to initialize them. A quick check to see if this fixes the issue would be
to comment out the init of irq4 and irq5 in SX1276IoIrqInit():
#if 0
rc = hal_gpio_irq_init(SX1276_DIO4, irqHandlers[4], NULL,
HAL_GPIO_TRIG_RISING, HAL_GPIO_PULL_NONE);
assert(rc == 0);
hal_gpio_irq_enable(SX1276_DIO4);
rc = hal_gpio_irq_init(SX1276_DIO5, irqHandlers[5], NULL,
HAL_GPIO_TRIG_RISING, HAL_GPIO_PULL_NONE);
assert(rc == 0);
hal_gpio_irq_enable(SX1276_DIO5);
#endif
That should get you past the assert you see and get you to the next one :-)
