Team,
I found the following post regarding McSPI boot in SPI mode: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1071789/am62x-mcspi-d0-and-d1-direction-in-spi-bootmode
>>> D0 is MISO, and D1 is MOSI. It is not configurable
Is this the same when booting from OSPI in SPI mode? The TRM is not clear about this. Where can this info be found, which pin is MISO and which MOSI?
Thanks,
Robert
Hi Robert
For OSPI booting in SPI mode (i will clarify this in the next TRM revision):
OSPI0_D0: MOSI, Data transfers FROM the processor TO the flash device
OPSI0_D1: MISO, Data transfers TO the processor FROM the flash device
Note that the McSPI module is a completely different hardware module in the MCU domain and doesn't have boot capabilities.
Regards,
James
