[Urgent] Question about SRAM ECC

[harry_choi]

Dear Community,

I have several questions about SRAM ECC.

1) Is the ECC on SRAM enabled by default? Which codes make the ECC on SRAM enabled?

2) I'm trying to launch A53 core from M7 core, so I have to copy u-boot code to SRAM. But I knew that I have to enable __RAM_INIT flag in linker to init ECC. If not, the exception happened when I copy the u-boot code to SRAM. Is that normal symptom?

3) Initializing SRAM area(uboot code to be copied) during booting time takes so long time. Is there any fast way to reduce SRAM initialization time? or is there any way to disable ECC on special area of SRAM?

Best Regards,

Harry

I found the solution by myself.
