TMS320F28075 device boot modes: flash and spi

Other Parts Discussed in Thread: CONTROLSUITE

Device boot rom support booting from flash and various interfaces like uart, spi, i2c, etc.

Currently the default boot pins can detect to boot from either uart or flash, is it possible to change it to either spi or flash instead?

If not, can I call the SPI_Boot in boot rom directly to force it to load from spi?

Appreciate any advice on this, thanks!

Hi Chow,

No, we can not change the boot pin definition from UART BOOT to SPI BOOT but user can change the flash boot option to SPI boot option by programming the Zx-BOOTCTRL location in USER OTP.

If not, can I call the SPI_Boot in boot rom directly to force it to load from spi?

Yes, user can always call the SPI_Boot routine in ROM from their application code to load the code from SPI.

Thank you for the quick response, could you point me to the location of the header file that declares the SPI_Boot routine? I am searching the Ti-RTOS but haven't been able to find it yet, thanks.

Edited - Oops, I think saw a similar question being answered, so I will download the ControlSuite to check.

Hi Vivek,

I have downloaded the controlSUITE and found the boot rom folder, but there is no folder for 2807x. If I have to request for it, pls let me know how to proceed. Otherwise do you have any other suggestions?

Best regards,
KahWai

Hi,

You can use the files available inside "F2837x_bootROM\cpu01-bootROM" folders to link.
