TMS320F2800157-Q1: Code not retaining after power cycling in the Microcontroller even if i am loading from through FLASH

Control card has TMS320F2800157-Q1 micro controller..

Kindly reply ASAP

Hi Muntaha,

Can you please help confirm that your controlcard is in Flash boot mode? The pins on switch 4 (S4) should both be up.

Gpio 24 and GPIO 32 is pulled down and we want it down only. As per the requirement?

What can i do to metigate this issue..

we only have to pull it up when we want in the operation

we want to be GPIOs pulled down until we command it through the code

Hi Muntaha,

There is a way to do 'Zero Boot Mode Select Pins'. Please refer to the 'Boot Mode Example Use Cases' section within the F2800157x Technical reference manual (TRM) for the steps required. This will not require the use of any boot mode select pins and always have the device boot to Flash.

Best Regards,
