Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC. When hardware ECC is not enabled in CSOR, software ECC is now used.

Impact: Boot from IFC may not be successful if IFC_CS3 is used. Workaround: If IFC_CS3 is used, gate IFC_CS3 while booting from NAND or NOR. Also Software should select IFC_CS3 using PMUXCR[26:27] = 0x01.

When sum of the base address, defined by BA, and memory bank size, defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask CSPRn[BA] bits. Impact: This will impact booting when we are reprogramming CSPR0(BA) and AMASK0(AMASK) while executing from NOR Flash. Workaround: Re-programming of CSPR(BA) and AMASK is done while not executing from NOR Flash. The code which programs the BA and AMASK is executed from L2-SRAM.

Maybe you have to explain the code to me. LIke the compiler, I wonder where l2srbar gets initialized: Here is the declaration: ... 74 u32 *l2srbar, *dst, *src; ... First use of this variable is here: ... 139 for (i = 0; i < 1024; i++) 140 *l2srbar++ = *src++; ... Where is the initialization?

I apologize, now that I look at this I question what in the world is going on. Poonam, What's going on whit this code: dst = (u32 *) SRAM_BASE_ADDR; src = (u32 *) setup_ifc; for (i = 0; i < 1024; i++) *l2srbar++ = *src++; we don't use 'dst' as far as I can tell and 'l2srbar' is never initialized so what in the world are we writing to? - k ^ permalink raw reply [flat|nested] 17+ messages in thread
