TMS320C6745: NOR direct boot

Ajitha JK

Part Number: TMS320C6745

i have tried direct boot through NOR flash interface.

when doing so i got two EMA_CS2/ signals with address changing from 00,01,10&11 twice for EMA_BA0 & EMA_BA1. during this time EMA_A12 toEMA_A0 was "0000".

after the two EMA_cs2/ signal along with EMA_oe/ for reading a word twice the EMA_BA0 & EMA_BA1 was "11" and EMA_A12 toEMA_ A0 "0000".

there was no further signals in the EMIFA interface. what could be the reason? how can i proceed with instruction execution in direct boot mode?

Hello, here is a link to our application not for how to use the bootloader:

how are you flashing the NOR? We recommend that you use AISGen and the Serial Flashing Utility.

here is a wiki on the serial flash utility:

Hello, we will need more details. Is this a custom board? have you reviewed the documentation available online regarding the boot modes and how to properly configure for each? You need to ensure you have properly flashed the NOR and you need to be configured for NOR boot.
