F280025C +8323RS

DMC_BUILDLEVEL设置为DMC_LEVEL_4来构建和加载项目当接上电机时出现了moduleOverCurrent = 1 和 flagEnableRunAndIdentify =0 的情况

拆除电机后则不会出现moduleOverCurrent = 1 的情况这个该怎么解决呢

你好，我看到你有引用相同问题的帖子，帖子中FAE建议参数识别的时候不要加负载，你是否有参考？

另外，你的电机本身是运行正常的吗？

可以确定电机没有加负载之前用F28027f+8353RS 可以运行

之所以引用相同的帖子是我遇到相同的问题没有看到后续是如何解决的

电机没有负载 C9 C10 C11 加了 47nf 还有什么地方没有遗漏了吗，这个是什么原因呢

你好，这是对方回复：

Please take a look at the lab guide and follow it to connect the kits and run the lab from build level 1. Make sure that the related switches are set correctly on LAUNCHXL-F280025C, and the connection is as below shown in the lab guide. Universal Project and Lab User’s Guide: https://www.ti.com/lit/spruj26

• For more details about the BOOSTXL-DRV8323RS, see the User's Guide for the EVM.

• Make sure that the following items are completed as described below, and then connect the BOOSTXLDRV8323RS

to J1/J3 and J4/J2 of the LAUNCHXL-F280025C as shown in Figure 2-7.

– Populate C9, C10, and C11 with a 47nF capacitor.

– Bend J3-29 and J3-30 of the LAUNCHXL-F280025C90 degrees so that they are not connected to the

BOOSTXL-DRV8323RS as shown in Figure 2-5.

Please make sure that the switches are set correctly as shown in lab guide as below also, especially the S2.

Install jumpers on JP1, JP2, JP3 and J101 for the power supply and debug JTAG. And jumpers on JP8 for the power supply of DAC128S board if used.
For S2, position the SEL1 (LEFT) switch UP (1) to route GPIO28 and GPIO29 to the BoosterPack connector, and position the SEL2 (RIGHT) switch UP (1) to rout GPIO16 and GPIO17 to the virtual COM port of the XDS110 debugger.
For S3, position the SEL1(LEFT) switch DOWN to pull GPIO24 low to logic 0, and position the SEL2(RIGHT) switch UP to pull GPIO32 high to logic 1 to put the F280025C into wait boot mode for reducing the risk of connectivity issues or a previous loaded code execution.
For S4, set S4 to DOWN (on), GPIO32 and GPIO33 are routed to the CAN transceiver to J14 CAN interface if the pre-define symbols "CMD_CAN_EN" is set in project properties.
For S5, position the SEL1(LEFT) switch DOWN to route GPIO44/37/43 to eQEP1 for the encoder interface on J12, and position the SEL2 (RIGHT) switch DOWN to route GPIO14/25/26 to eQEP2 for the Hall sensor interface on J13.

是按照文档要求来的

moduleOverCurrent = 1 是在接上电机后才出现的，
