Processor: TMS320DM6437
Inquiry: How is the PSP NAND Device Driver configured to so it can wrte to selected Block. It appears that any attempt to write erases all the NAND Blocks
(e.g., all 0 to 1023 blocks of a1Gbit NAND). The example in C:\dvsdk_1_01_00_15\psp_1_00_02_00\pspdrivers\drivers\nand use the following (partial listing):
if (1 == Erase)
{
result = PSP_nandErase(hNand); /* Erases all the sectors except protected blocks */
/* See Line 968, ddc_nandFtl.c: pNandState->noOfBlocks, pNandState->protectedBlks*/
if (PSP_SOK != result)
{
LOG_printf(&trace,"\nNAND :Driver Error Status = %d\n", result);
return FALSE;
}
else
{
LOG_printf(&trace,"NAND :NAND Flash erase Success.\n");
}
}
in ddc_nandFtl.c, there is no user contorl over the starting and ending block# values. The erasure starts at 0 to 1023, in the case of tne NAND chip in my system.
it is no clear how to configure the driver to erase specific number of blocks. Could someone please provide some insigt?
