This prevents the MCU from starting the application. Very similar situation is already described in the 6 years old topic: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/926219/tms320f28069-xds110-debugger-keeping-the-dsp-at-reset-at-power-up-and-letting-the-dsp-run-at-erase-load-via-uniflash-or-ccs I have tried various reset and connection settings within UniFlash (v: 9.4.1), but the Reset pin remains stuck at LOW regardless of the configuration (Run Target After Program Load, Reset Target after program load, ...). When using the MSPM0C1106 LaunchPad, the behavior is correct and the MCU starts as expected after flashing. My target is connected over Debug connector 20pin reduced to 14pin using signals NTRST, GND, VTRef, SWDIO and SWCLK. After some investigation I discovered that calling the dbgjtag.exe utility with the -Y blink argument immediately after the flashing process releases the Reset pin, and the MCU starts running normally: The current workaround looks like this: dslite.bat --config=MSPM0C1105.ccxml -e -f release.hex -u dbgjtag.exe -f MSP432_XDS110_JTAG.dat -Y blink The additional options like -Y power, -Y power,supply=on/off or -Y reset does nothing. Only the -Y blink can release the reset pin in all cases. Looks like it is because it takes longer time. I was playing with dbgjtag.exe utility to be able to control the XDS110 and I found out the MSP432_XDS110_JTAG.dat file in IAR debugger files for TI. This is the only file which is working for me for the XDS110 with MSPM0C1105. Even if it is for MSP432 I can see the LEDs are blinking and this somehow is releasing the reset pin. I also tried the utility xds110reset.exe but nothing happend on NTRST (pin 2) or NRESET (pin 15). The utility processed the command but it looks like it is ignored by XDS110. It seems like the debug session is not being terminated correctly by Uniflash, or the probe is not releasing the reset line. It does not matter if Uniflash GUI or dslite.bat is used the behaviour is always the same. Is this a known issue with the XDS110 driver or UniFlash specifically for the MSPM0C series? Any guidance on how to resolve this without the dbgjtag.exe workaround would be appreciated. In att. I'm providing all my cfg. files.

I am currently looking into your question about the "binary output requires IMAGE and ROMS directives" warning to understand when the hex2000 started emitting the warning and why. In the meantime, can you provide a reproducible example that demonstrates the generation of the warning, along with the command-line that you used to invoke the hex2000 utility?

The remote end did not respond in time.All UDCs in use (1 available), use the unbind command The first line is printed from usb_gadget_probe_driver(), while the last line is printed from usb_eth_start(). Before we dig into it, can you please - what is the old U-Boot version before you move to 2025.01? what is the console log when the old version of u-boot-spl-restore.bin was transferred to the board and running? - do you have a Beaglebone Black board or any of AM335x EVM so that you can test with your 2025.01 U-Boot to see if u-boot-spl-restore.bin has the same issue?Forum Post: RE: F29H850TU: can interrupt is not getting triggered.https://e2e.ti.com/support/tools/code-composer-studio-group/ccs/f/code-composer-studio-forum/1640163/f29h850tu-can-interrupt-is-not-getting-triggered/6334641Wed, 06 May 2026 12:42:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:873f8f21-75ce-4d45-a011-26fab18e835fPranav SiddappaHi Sayali, Since ISR is not getting triggered, there is an issue with how the message is received. There might be the following issues: Can you recheck the ID of the message? Can you confirm if the Transceiver is connected correctly? Also try tracing the signal you are sending to the CAN node via oscilloscope to check if the message is actually being sent out There is a mismatch between the CAN mode and element size. Element size is 64 bytes and CAN FD mode is not enabled. Confirm which mode you want to use. As a last resort, try monitoring the RXBUF via the register window to confirm if the message has actually reached. Its tough for me to recreate this without the entire project app. If you could share it as a whole, i might be able to prove more insight.

Once the ISR functionality is confirmed, the same logic will be integrated into the main application code. In the current implementation, using LINE1 interrupt. RX FIFO1 new message interrupt , and TX event new message interrupt have been enabled. Within the ISR, a single LED is toggled to indicate interrupt execution, and a data transmission is performed as part of the interrupt handling routine. Please review and confirm whether any additional board-level configuration or hardware changes are required to ensure proper interrupt triggering and execution.

I started observing where it stopped, and so far, it has always been at the MSTOP instruction. Is there any way to prevent that one from stopping it when I connect? Please note that this only occurs when the emulator connects. If I tell it to go, it won't stop on subsequent occurrences.

If not, then by nature the CLA is halted until one of the tasks get triggered since there is no main loop. Another thing you can check is if you have a __mdebugstop(); line somewhere that the debugger is hitting on the CLA core.

Both have the “Halt the target on a connect” option unchecked. When I attach to the running system, CPU1 continues running as expected. But CPU1_CLA1 halts. Is there any way to prevent that? Thank you, EdTMS320F28388S
