Booting from NOR Flash

John_K — Mon, 29 Aug 2016 15:28:56 GMT

I am planning on booting from the (T1040) IFC_Bus using NOR Flash. The UM states that "Before fetching the first instruction from the NOR flash, the IFC flash timing registers are loaded with default timing parameters." My question is assuming default timing parameters is the reset setting of the IFC_FTIM0_CSn_NOR register which is reset to all 0's and all 0's is specified as reserved, how am I supposed to determine the timing of the boot accesses from IFC bus during reads after reset.

Thanks.

Look at the Table 24-4 of the T1040 Reference Manual Rev 1:

This Table shows IFC values for NAND and NOR RCW reading and NOR boot.

Have a great day,
