[PATCH] ARM: give more detailed information about data aborts
WebInterrupt -> CPU Freeze -> Stopped at Data Abort Handler. Keyword : CPU Freeze / Interrupt / Data Abort Exception / Slave AXI / Ethernet timer Interrupt. PROBLEM : PL -> PS Interrupt stops working after 1mn15 seconds or WORK IF call PRINT. Webbefore going back to my real world problem, which is hard to replicate, I also deliberately forced the CPU into a data abort. Just to see if I get a meaningful result. Works for synchronous aborts and expected not for asynchronous aborts. In CCS in combination with Segger's J-Link I wasn't able to read the USER_Registers. mondial relay valence 26000
Data Abort exception - ARM architecture family
WebApr 8, 2014 · An example of an imprecise data abort might be a data write which goes through a write buffer. In such a case, the eventual write to memory may come many cycles after the STR instruction which placed the data in the write buffer. In this situation, it is not generally possible to work backwards to identity the instruction. WebJan 23, 2014 · and bad_mode resets the cpu. One approach might be to raise flag before trying possible aborting address then in do_data_abort check the flag and instead of bad_mode and if that's the case lower the flag and continue with next instruction, which should check if flag was lowered or not. WebData Abort LR-8 FIQ, IRQ, prefetch Abort LR-4 SWI, Undefined Instruction LR The PC has advanced beyond the instruction causing the exception. Upon exit of the prefetch abort exception handler, software must re-load the PC back one instruction from the PC saved at the time of the exception. mondial relay vals les bains
