We use flashtool , when downloading the program to norflsh through s32G2 serial port 0, the serial port chip has been chaged, but 3 of the 5 boards appear to obtain the chip ID or display The Resolution error #3 is displayed when the algorithm is loaded.

The dialing code has been set to the all off state. After downloading the program through the burner, observe that the uart0 print message and receive information are normal.
What does the error #3 stand for? Are there special restrictions on the hardware of UART0, thank you.
我们使用Flash tool 软件,通过s32G的串口0下载程序到norflsh时,串口芯片已经更换,5块板子有三块出现在获取芯片ID或者加载算法时会显示Response error #3。
拨码已经调到all off 状态。通过烧录器下载程序后观察uart0打印信息和接收信息正常。
请问下载的error #3 代表什么?对于uart0 的硬件有无特别的限制,谢谢。
