The design uses a MSPM0G3105. The cpu is fresh from factory (it never been programmed with any code or configuration). All the signals to the 10-pin debug connector are connected as indicated in the documentation: Pin 1 = VTREF (connected to the board's 3.3V) Pin 2 = SWDIO Pin 4 = SWCLK Pins 3, 5, 7, 9 = GND Pin 10 = nRST The .ccxml file is configured for SWD Mode and Target Supplied Power. I even reduced the frequency to 100 kHz. In CCS, if I select Run/Debug Project, the session starts, but when it tries to load the program, it stalls at PT_LOAD[0]: 0 of 2344 at 0x0. I tried "Start Project-less Debut", then Connect Target on the CORTEX_M0P thread. After that, I get the same result if I go through Run/Load Program. I used the "Test Connections..." button in the advanced properties of the ccxml file and it says the SWD Mode Integrity test has succeeded. I get the same results if I use UniFlash. I verified my XDS110 USB probe is working properly with a LP-MSPM0G3507 Development Kit. It worked as expected and I was able to load and run a program in the CPU. I need help with this issue (I tried multiple PCBs).UniFlashMSPM0G3105MSPM0-SDKLP-MSPM0G3507https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1679061/mspm0-sdk-question-about-lin-behavior-mcal-1-0-lin-driver-1-5-0Thu, 03 Sep 2026 08:12:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1b3d90d4-51bd-4ace-a998-23e7413d8c30Youssef GhorabPart Number: MSPM0-SDK We are currently experiencing an issue after integrating LIN 1.5 with AUTOSAR 4.4 to support slave functionality. Our configuration is set up with Autobaud rate enabled (True) and an autobaudratethreshold of 2. However, we are observing systematic, random response error bit toggling on the LIN bus. During debugging, I noticed that the LIN driver is reporting both LIN_ERR_HEADER and LIN_ERR_RESP_STOPBIT. Could you please provide your insights or support on this behavior? Find attached MCU and Lin Xdm files config.zip After analaysis we found out The root cause of the timing issues and the resulting LIN_ERR_HEADER tolerance violations is directly tied to the use of the internal clock. The Hardware Reality: In your Mcu_PBcfg.c file, your microcontroller is configured to use the internal system oscillator ( MCU_MCLK_SOURCE_SYSOSC ) and the external clock is explicitly disabled ( Mcu_ClkExternalClkEnabled = FALSE ) . Internal RC oscillators naturally drift due to temperature changes and manufacturing tolerances. The Measurement Flaw: The TI LIN driver uses your microcontroller's internal clock to count the width of the master's incoming sync pulses . If your internal clock speeds up or slows down due to drift, the number of counted ticks changes, making it look like the master's timing is wrong . The Strict Driver: The 1.5.0 version of the Lin_Priv.c driver strictly enforces a +- 1.5% timing tolerance rule . Because your internal clock drifts more than 1.5%, the measurement math fails, and the driver throws a LIN_ERR_HEADERMSPM0-SDKhttps://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1678681/tpsm843b22-details-about-effeciency-at-15v-is-a-input-and-iout-is-0-05v-and-vout-is-5v/6470911Wed, 02 Sep 2026 15:14:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:63620fa9-8b45-4b5f-85eb-f3e411ff98c3Carson Harramanwhat is your switching frequency?

However, I have the oscilloscope waveform from the dead-time verification before the EVM failed. The measured dead-time was approximately 35 ns at 100 kHz / 30% duty cycle. I have attached the waveform for reference. During the test, I performed live frequency tuning while the PWM output was active. Could this have caused a temporary abnormal PWM condition or insufficient dead-time, potentially resulting in shoot-through? I would appreciate your thoughts on whether this could be a possible cause of the shoot-through.
