Hi,
We now find DMA RAM SECDED 1-Bit ECC Error Fault injection and DMA RAM SECDED 2-Bit ECC Error Fault injection generate the same fault and triggger the same ESM group1 interrupt(ESM1.3).
Can you help check the SDL code?
Step1. we do the DMA RAM SECDED 2-Bit ECC Error Fault injection. It's as expecting.
Step2. we do the DMA RAM SECDED 1-Bit ECC Error Fault injection. The stat1 register is still 0x00000008(bit3 indicates ESM_G1ERR_DMA_ECC_UNCORR) It's unexpected.
Hi Shenruming,
I wish you did the both testings separately, i hope you didn't perform single bit error right after double bit error in the same code?
Actually, for single bit DMA error ESM1.82 should need to be SET.
Did you check the ESM1.82 status for both the testings?

Hi Jagadish,
In fact, even if I just do DMA ECC 1bit error forcing, it also trigger ESM1.3.
By the way, another urgent case needs you confirm as soon as possibile. It has been delayed for days.
It's about STC test including polling test "STC1_RUN/STC2_RUN" and error forcing test "STC1_COMPARE_SELFCHECK/STC2_COMPARE_SELFCHECK".
