The customer¡¯s R-Core is equipped with an AUTOSAR platform and performs multiple tasks simultaneously. Currently, there have been reports of intermittent failures in I2C interrupts when communicating with the PMIC on the R-Core. This issue occurs randomly during communication, and unstable I2C signal waveforms, as shown in the figure below, have also been observed. Our sample code uses a dummy RTOS, so please verify whether a high load on the R-Core affects the I2C communication.

Could someone assist us with the environment setup? we need support on which binary to use and how to conduct testing in the V4H environment, as we are not very familiar with these aspects. If explanations are given to the team, we can also provide them in Japanese. 1010 - WriteÇÒ ¶§ StuckÀÌ ¹ß»ý, Read±îÁö °¡Áö ¸øÇÔ. PMIC - ReadÇÒ¶§¸¸ StuckÀÌ ¹ß»ýÇÔ µð½Ã¸®¾óÀ» Ch5¿¡ ¹°·Á¼­ Test ÇÒ ¿¹Á¤.
