Part Number: TM4C1290NCPDT
Tool/software: TI-RTOS
TI-RTOS. I'm getting a fault error in my code, it prints out the FSR, HFSR, DFSR, MMAR, BFAR and AFSR values. Those registers don't seem to be documented in the CPU manual, there's a Fault Exceptions tutorial from armKEIL that lists a few of these registers. Where is the documentation on these registers?
Thanks
Please find below in the datasheet. The names may not exactly match what is printed in the TI-RTOS message. The names that are printed out in TI-RTOS are the direct names used in ARM Cortex-M4 processor TRM. You can find the TRM at http://infocenter.arm.com/help/topic/com.arm.doc.ddi0439b/DDI0439B_cortex_m4_r0p0_trm.pdf.
Many of times when you get a fault, it is because you are accessing a peripheral that is not yet enabled. This can lead to a hard fault. It is also possible that you get a memory fault because your stack overflows. Normally, you can increase the stack size just to see if it makes the fault go away and confirm if the fault was indeed due to a memory. In TI-RTOS you can use the ROV to see if your task overflow the allocated stack size.
The below two links will be also helpful.
