Hello

I am working on bringing up a custom C6657 board which I need to boot from SPI NOR Flash

Hi Deutshein,

It is possible to boot from SPI NOR Flash without using the IBL that is on the I2C EEPROM.

Please take a look at this forum post: C6657 SPI boot problem.

Hope this helps.

Regards,

-Jon

yes or no

Yes.

In the post from the link I provided, there is some sample code that successfully boots from SPI NOR Flash without using an I2C EEPROM.

If you are using a production EVM, this example will work.

Also, if you are using a pre-production EVM, you can use the version 03 of the FPGA firmware (already on the prodcution EVM) provided by the board manufacturer to program the FPGA to so that the EVM will NOT use the IBL on the I2C EEPROM: https://www.einfochips.com/index.php/partnerships/texas-instruments/tms320c6657-evm#5-resources
