Interrupt Stack Overflow

MQXuser — Wed, 26 Aug 2009 23:47:44 GMT

Have any of you seen this error?,

My ISRs are very small and dont require big amount of RAM.

Any hints about what could be going on?

TAD shows the following:

Stack Overflow Interrupt Stack, Stack Base 0x20000bc4, Stack Limit 0x200007c4

LWMemory Error LWMemory 0x0 corrupted

Partition Error Partition 0x202afff4 corrupted

LWEvent Error LWEvent 0x0 corrupted

LWSem Error LWSem 0x200006f4

Thanks

What about Unhandled Interrupt error?

Shell task is giving me that error when more interrupts are added to the program.

Any clues?

Hello,

seems like memory is overwritten by something. Try to use _int_install_unexpected_isr(), this will send you some useful information about failing interrupt via STDOUT.
