C5509a board connection and example program issues [Copy link]

I am using CSS4.1, the board is 5509a, and the emulator is XDS100V2. This error is reported when connecting to the board. I have searched a lot on the Internet but couldn’t find the answer. I would like to ask the experts for help. Error connecting to the target: Error 0x80000242/-1023 Fatal Error during: Memory, Initialization, OCS, PTI_ERR_IROP_CMD Error Occured at 0x000000BE I have two identical boards, 5509a, one can connect normally (I have been using this board for development), and then I changed to another board. When CCS connects, it reports an error (cannot connect)!! When I changed to the original board, I can still connect successfully. 。 。 。 Experts, can this confirm that it is a problem with the board hardware? (I didn’t make any changes in the middle) The second problem is that when I executed the routine echo provided by the manufacturer, I found that when the I2C program initialized the AIC32 chip, the I2C status register was not set. When initializing the AIC32 chip, except for the first step AIC23_RESET_REG, which can execute through the loop below, all other configurations are stuck in the loop below. for (i = 0; i < len ; i++) { pI2c -> icdxr=dataBuff[i]; while(!(pI2c -> icstr & ICSTR_ICXRDY)); } It is stuck in the while loop. . . This is pure software development. How can I find out whether the configuration has been sent to the AIC32 chip (proving that there is a problem with the I2C status register), or check whether I2C has sent data (proving that there is a problem with the I2C hardware) More operations
