|Summary||08347: vf2o, overrev, sgt24h: "Fatal error: I960: 2f2f2f2e: Unhandled 00" during Self-Test of CPU working RAM|
During Self-Test of CPU working RAM, i960 CPU seems jump to some random address, causing either Crash(overrev/sgt24h/(sometimes)vf2o), or Failure of RAM test(all vf2 revisions).
Occasionally, vf2x CAN pass its CPU RAM test.
Did some study in debug mode: seems when the ram-test code writing to i960 Interrupt Table area, an unexpected INT happens.
|Steps To Reproduce||When demo (means all inits should have been done), press F2 to enter self-test, then select memory test.|
|Regression Version||At least 0.185|
|Affected Sets / Systems||vf2o, overrev, sgt24h|
