Tool/software:
Hi Team,
I am trying to run I2C3 with a receive interrupt in slave mode on the AM263x LP kit, but we are not able to call the ISR function. Could you please let me know what I might be missing?
In addition, I am facing another issue — the I2C communication is happening and data is being exchanged between I2C_ICDXR and I2C_CDRR, but the data is not being copied into the variable. Could you let me know why this might be happening?
I am sharing my main.c, SysConfig file, and some UART log files for your reference. Please check and advise.
Note-: I have shorted I2C1 and I2C3 just only for reduce the HW connection. I am facing same issue with other MCU I2C also.
