MSPM0-SDK: MSPM0G3507 串口DMA进行不定长数据收发

biza inc — Wed, 06 May 2026 15:28:32 GMT

Part Number: MSPM0-SDK
Other Parts Discussed in Thread: MSPM0G3507

HI，我在基于MSPM0G3507的串口+DMA实现不定长数据的收发，由于MSPM0G3507的寄存器特殊性，当使用DMA时，因为DMA及时半空FIFO所以超时中断无法触发，如果引入定时器轮询会浪费外设的同时效率不高，频繁的接收中断也会拉低CPU的效率。

我看到并参考：https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/1220244/faq-uart-rx-ms-level-timeout-realization-based-on-event-for-mspm0?tisearch=e2e-sitesearch&keymatch=UART%20timeout%20MSPM0 来进行设计，但是发现偶尔会出现字节多收，理论上此拓扑应该能行的通，但是我试验多次，发现一旦数据多了还是会多收字节，表现为DMASZ的数量跟实际发送不一致。

对于MSPM0G3507的架构特殊性，我严重怀疑TI的芯片设计是否有用过串口。

此问题依然存在，最后我只能使用串口中断+超时中断，使用仅仅4字深的FIFO来接收数据。

各位如果有更好的建议，还请让我知道，谢谢！

TDA4VM: Inquiry About Online Debugging Support for DCCSetup_2023_10_10.exe and Alternative ISP Tuning Tools

tang yuanzheng — Fri, 10 Apr 2026 02:46:47 GMT

Part Number: TDA4VM

Hi TI Team,

I’m currently working with the TDA4VM ISP pipeline and using the DCCSetup_2023_10_10.exe tool to generate DCC configuration files for image tuning.

I have two questions:

Does DCCSetup_2023_10_10.exe support online (real-time) debugging?
Specifically, can I adjust ISP parameters (e.g., GLBCE, noise reduction, color correction) in real time while the system is running, and see the changes reflected immediately in the output video stream?
Are there other recommended tools or methods for online ISP tuning on TDA4VM?
I’ve heard about the TI Image Tuning Tool (ITT) and ti_tuning_app, but I’m not sure if they are compatible with this version of DCCSetup or the latest Processor SDK (e.g., PSDK 8.x or 9.x). Could you please clarify the current best practice for real-time ISP parameter tuning?

Any guidance or documentation links would be greatly appreciated!

Best regards,
Shenzhen Jueming Artificial Intelligence Co., Ltd.

TIDM-02013: Voltage distortion across the switching transistor under sub-resonant operation

Wang Xuesong — Tue, 07 Apr 2026 11:32:27 GMT

Part Number: TIDM-02013

Dear expert.

When the frequency is below 400 kHz, the voltage Vds across the secondary-side switches exhibits sudden rises and falls. As the frequency decreases, the peak values of these sudden changes become larger. What is this related to? Is this a normal phenomenon?

Purple waveform: drain-source voltage Vds across the switching transistor.

Blue waveform: secondary-side current.

TIDM-02013: Issues of Relay Closing and Overcurrent Protection Triggering on the Circuit Board Caused by Driver Loss in the PFC Stage

Wang Xuesong — Tue, 10 Mar 2026 12:32:14 GMT

Part Number: TIDM-02013
Other Parts Discussed in Thread: SFRA

Hello,

I am currently validating Experiment 3 of the PFC stage, with TTPLPFC_ac_cur_ref_pu set to 0.02.

The boost routine initiates when TTPLPFC_vBus_sensed_Volts > 110 V.

At no-load condition:

TTPLPFC_vBus_sensed_Volts can rise to 175 V; however, gate drive loss occurs as the input AC voltage enters its positive half-cycle.
With a 500 Ω load:

TTPLPFC_vBus_sensed_Volts can boost up to 135 V, but after maintaining this level for a few seconds, it begins to decline, eventually dropping below 110 V.

Throughout this process, the input AC voltage remains stable at 78 V.
Relay closing during boost:

Closing the relay during the boost phase triggers overcurrent protection (OCP) on the PCB.

Consequently, the relay remained open in all the aforementioned tests. Freewheeling was implemented via a bypassed thermistor, with each power-on duration strictly controlled within 10 seconds.
Waveform analysis & query:

From the measured waveforms, a definite phase difference between the voltage and current is still observable.

Is it feasible to eliminate this phase discrepancy and achieve phase alignment by adjusting the compensation capacitor?

I look forward to your prompt reply.

我正在开发烧录器，用于烧录MSPM0L1228芯片。烧录客户文件，客户文件区域包含NONMAIN的BCR区域，BOOTCFG0的数据为：0xaabbccdd，PWDDEBUGLOCK区域也需要烧数据。我的烧录器将数据写入后，执行回读校验，发现没有读到数据，写入和回读操作之间没有复位操作。请问这样是正常的吗？我该如何校验我写入的数据是否正确？

PS：我验证过，如果BOOTCFG0=0xaabbaabb，PWDDEBUGLOCK区域都是0xffffffff，烧录和校验都是正常的。

如果BOOTCFG0=0xaabbaabb，PWDDEBUGLOCK区域保留密码数据，会回读失败。

TIDM-02013: Research on the Synchronous Rectification Technology of the CLLLC Resonant Converter

Wang Xuesong — Tue, 13 Jan 2026 13:28:44 GMT

Part Number: TIDM-02013
Other Parts Discussed in Thread: PMP22650

The blue waveform represents the secondary - side current, while the others are the two - channel secondary - side driving signals. As shown in the figure, the synchronous rectification (SR) operation should be functioning properly. However, during the experiment, when the secondary - side driving was enabled, the input voltage rose sharply. Under this condition, the input voltage was set at 10 V with a connected load of 20 Ω, but the input current had already reached 3 A. Subsequently, when I replaced the load resistor with a 100 - Ω one, the input voltage and current remained unchanged. Therefore, it is likely that a short - circuit fault occurred in a certain part of the circuit. When the secondary - side driving was disabled and the secondary side operated temporarily as a diode bridge, both the input and output voltages and currents returned to normal levels.

In summary, the current fault is probably caused by a short circuit in a certain circuit triggered by the enabling of the secondary - side driving. (It should be specially noted that since a Rogowski coil of the same model could not be found, a Hall sensor was adopted as the current detection scheme instead, and the blue secondary - side current waveform shown is the signal processed by an operational amplifier.) At present, I consider the possible causes of this problem as follows: 1. The current detection scheme; 2. Insufficient driving delay between the primary and secondary sides; 3. Improper synchronous rectification thresholds (set at 2100 and 2000) and insufficient blanking time.

Your reply would be highly appreciated, as this issue is of great importance to me. Thank you.

AM2432: The question about the long processing time of EtherCAT mailbox data frames

Part Number: AM2432

hello,

The SDK version is 09.02.00.15 and the example is ethercat_slave_beckhoff_ssc_demo.

When testing email communication, we found that the interval between the frame of the email request sent by the master and the frame returned by the slave after processing was about 2ms. As shown in the following picture, the time it takes for cnt to change from 0 to 1.

Why does the processing time take so long?

We tested other chips and found that the processing time was probably within 200us.

TIDM-02013: CLLLC Secondary Side Voltage Protection Issue

Wang Xuesong — Fri, 19 Dec 2025 11:37:54 GMT

Part Number: TIDM-02013

Hello, expert! I need your help. when I conducted the experiment with the secondary output protection enabled, the following phenomena occurred:

When the secondary side voltage rose to 350V, the secondary overvoltage protection was triggered (the overvoltage protection threshold was set to 450V at this time).
After changing the overvoltage protection threshold to 400V, the protection was triggered when the secondary side voltage rose to 300V.
After changing the overvoltage protection threshold to 480V, the protection was still triggered when the secondary output voltage reached 350V.

In the above experiments, the ADC sampling values of the secondary side voltage displayed in the real-time monitoring window were consistent with the actual values.

What link could be causing this problem? When the output voltage reaches 350V, does the converted sampling value exceed 4096?
