Hello

In sdl_ex_ram_ecc_parity_test.c file, in runCorrectableECCTest I need to know why you looped from 0 to 16, However, the variable you try to corrupt is 32 bits.

same for runUncorrectableECCTest.

AHashem,

Apologies for the delay, I need to get some others on the team looped into this question who have some more experience with the SDL.

Best,
Matthew

Helo, I face the same question in the past,

If you have a look at RAM_DATA_SINGLE_BIT, you will see that 2 bit are flip, one for the first 16 bits, the second one for the upper 16bits.

Using this, the loop from 0 to 16 cover the 32 bits..

Yes, Manu36 explained it. For reference, here's the #define for RAM_DATA_SINGLE_BIT:

#define RAM_DATA_SINGLE_BIT     0x00010001UL // 1-bit mask in both words
