Hello everyone. Recently, the IMC101T-T038 chip was used to control a permanent magnet synchronous motor, and an MCU was used to communicate with the IMC101T-T038 through the UART port. After several months of operation, it was discovered that the chip was unable to communicate. The on-site inspection revealed that the MCU had sent a message to IMC101T-T038. The IMC101T-T038 had no response. The oscilloscope was used to check the transmission and reception foot waveforms. The MCU had transmitted waveforms, and the IMC101T-T038 did not respond to the waveforms. Communication returns to normal after the power is turned on again. The firmware burned by IMC101T-T038 is IMC101T-T038_A_v1.03.03.ldf

I just discovered on Infineon's official website that the IMC101T-T038_v1.03.07_releaseNotes document has the following instructions. Please ask the experts to help me to see if this problem in the MC101T-T038_A_v1.03.03.ldf firmware is causing the IMC101T-T038 to fail to communicate with the MCU. Thank you!

Hello, if the V1.03.03 version of the firmware has been running continuously for more than 149 days, UART may not be able to communicate. We recommend that you upgrade your firmware to the latest version.

Hello,

I'm already consulting a product-side engineer and will get back to you when I have the results.
