Hello Community
we are using MT29F256G08AUCAB NAND Flash Memory in Our Custom Board and that we Connected with FMC Signal.
Also am using HAL NAND Library to Program NAND Flash but there are Several doubts what HCLK Represent and What Value we have to Configure for these below timing and what Basis ?
ComSpaceTiming.SetupTime =
ComSpaceTiming.WaitSetupTime =
ComSpaceTiming.HoldSetupTime = ;
ComSpaceTiming.HiZSetupTime = ;
/* AttSpaceTiming */
AttSpaceTiming.SetupTime = ;
AttSpaceTiming.WaitSetupTime = ;
AttSpaceTiming.HoldSetupTime = ;
AttSpaceTiming.HiZSetupTime = ;
PLL Clock is 180 Mhz
Oscillator Clock 24MHz
As there was no Example for NAND Flash Device in STm32Cube. so we can't Decide what Value we have to Give.
Kindly Advised Accordingly for it.
Am Attaching NAND Flash DataSheet
Thank You

Hi,
I'm using Micron NAND Flash (32Gb) with the default settings in CubeMX. it works.
hnand1.Init.NandBank = FMC_NAND_BANK3;
hnand1.Init.Waitfeature = FMC_NAND_WAIT_FEATURE_ENABLE;
hnand1.Init.MemoryDataWidth = FMC_NAND_MEM_BUS_WIDTH_8;
hnand1.Init.EccComputation = FMC_NAND_ECC_ENABLE;
hnand1.Init.ECCPageSize = FMC_NAND_ECC_PAGE_SIZE_512BYTE;
hnand1.Init.TCLRSetupTime = 0;
hnand1.Init.TARSetupTime = 0;
/* hnand1.Config */
hnand1.Config.PageSize = 8192;
hnand1.Config.SpareAreaSize = 448;
hnand1.Config.BlockSize = 128;
hnand1.Config.BlockNbr = 4096;
hnand1.Config.PlaneNbr = 2;
hnand1.Config.PlaneSize = 4096;
hnand1.Config.ExtraCommandEnable = DISABLE;
/* ComSpaceTiming */
ComSpaceTiming.SetupTime = 252;
ComSpaceTiming.WaitSetupTime = 252;
ComSpaceTiming.HoldSetupTime = 252;
ComSpaceTiming.HiZSetupTime = 252;
/* AttSpaceTiming */
AttSpaceTiming.SetupTime = 252;
AttSpaceTiming.WaitSetupTime = 252;
AttSpaceTiming.HoldSetupTime = 252;
AttSpaceTiming.HiZSetupTime = 252;

Hello Texram
Thank You for you Suggestion
Can i know one more thing, how much Crystal Clock you Given to Micro Controller and which STm library used in Code?
Also on which Basis you decided 252 for Setup time?
or Just used hit and Trial Method ?
