Hi, Anthony：
Glad to see your reply, the SP in the TMS570LS3137 will minus from the top(for example, the IRQ stack is from 0x08001200-0x08001500, the SP will start from 1500, then minus proper value when needed until 0x08001200,if there is still some space needed, it will enter to the FIQ stack(0x08001100-0x08001200)), while the dabort stack address is 0x08001500-0x08001600, I don't know why the SP move there?
I thought that the TMS570LS3137 may have some internal rules that when a dabort exception happens, the SP will move to the dabort area and if undefined entry exception happens, the undefined stack entered. Is that correct?
