Please guide me, I can't find the F280049 Flash file, on TMS320F280049 when using Uniflash it will only work once, after reset it won't work.

Please guide me, I can't find the F280049 Flash file, on TMS320F280049 when using Uniflash it will only work once, after reset it won't work. After reset, it might be from the MCU boosting from RAM?

Hi,
There may be multiple reasons for the executable not running after power cycle
  • If the executable is generated with Boot from RAM, it will not work after power cycle. To check this setting in Simulink, navigate to: Model Configuration Parameters → Hardware Implementation → Target hardware resources → Build options
  • Boot from Flash = Enabled/True
  • The other possiblity is the boot pins on the control card or the launchpad is not set correctly. For example, this is the boot pin configuration mentioned in the launchpad user guide
Boot Mode Pins on F280049:
GPIO24 = BOOTCTRL Pin 0
GPIO32 = BOOTCTRL Pin 1
  • Validate this properly by looking at Launchpad or control card user guide
If you are still facing the same issue even after configuring these two correctly, validate whether flashing is correct with the Code Composer Studio instead of Uniflash or try to flash any CCS example through uniflash instead of Code Composer Studio
Please note: If the Flashing works in Code Composer Studio but not in UniFlash, you can check your query on the TI E2E Community Forum for specialized support regarding UniFlash specific issues.
Best regards,
Aditya
