Part Number: TMS320F28377S

Hi, I just built a board with TMS320f28377s. I used launchpad as a reference. I can program it via DXS110 USB Debug Probe. But when I reset the board or power it on and off it does not come back, and I must reprogram it in ram of flash configuration. Please see the schematics.

Hi,

On reset, all the RAMs are cleared hence you need to re-programmed the RAM. If you have application programmed in Flash then it should work as long as you have correct BOOTPIN setting (boot to flash). Check the same on your board.

Hi Vivek,

Should i pull up GPIO 72 and GPIO84 to 3.3V? Do i need to program any other registers in BOOTCTRL?

thanks vadim

Yes, pull GPIO72/84 pin high to set BOOT from flash.
