[PATCH V7 04/10] arm64: exception: handle Synchronous External Abort
WebIn the concrete case of a data abort exception the "data fault status register reads" 0x00001008. Hence the 5-bit status equals 0b01000 which indicates an "Synchronous External Abort" for which the VAR is supposed to be valid. Furthermore it shows it's a read access. Since it's an external abort, SD-Bit = 1 means it's an "AXI Slave error". WebOct 9, 2024 · Absolutely, char *buffer=new char[SIZE], but this will possibly leak.Is SIZE fixed? Some library functions can not be used (like new) in an interrupt reliably.You have to do this elsewhere. The new and all heap management need to run 'atomically'.
