If I want to boot from a NAND flash. At which Pin of the Sitara do I have to connect the Busy Pin from the Flash if I select with SYSBOOT[8] = 0 Wait mux option 0.
And at which Pin if I have selected SYSBOOT[8] = 1?
This is not clear from the datasheet because it doesn’t say what the Wait mux option 0 and 1 means. It could mean selecting the gpmc_wait0 or gpmc_wait1 pin or it could mean selecting Pin B12 or A2 for gpmc_wait0.
I have read it the first time and the tables DO provide the answer:
Pins are named after their functionality in Mode 0 (Table 4-10 in the AM437x Datasheet Rev. D):
GPMC_WAIT0 is pin A2. This pin is configured in Mode 0 by the ROM code when Wait mux option 0 is selected (SYSBOOT[8] = 0).
GPMC_CSN3 is pin B12. This pin is configured in Mode 1 by the ROM code when Wait mux option 1 is selected (SYSBOOT[8] = 1).
The Wait signal for NAND boot is always GPMC_WAIT0.
