Hi, I'm currently searching the bug that prevents the STRG-C break of the GDB stub. (LPC2294) I discovered that the (global) IRQ-Disable bit in the cpsr register is set. Because of that the STRG-C interrupt of the debug channel is unable to occure. I searched in the whole code but did not found the part where this IRQ-Disable bit (bit 7) is cleared. Maybe you have a hint for me? Where should I add the patch for that? In the cyg_hal_plf_serial_init() function? (The HAL_INTERRUPT_(U)MASK functions work only with the interrupt controller) Whats about the other packages that uses the interrupts? (I currently use the minimal config to search the bug.) Where and when do they disable the global interrupt-disable flag?
Thank you, Martin L.
