Other Parts Discussed in Thread: AWR6843
Tool/software:
Hi all,
I have recently designed a custom board based on the AWR6843AOP radar chip. The board powers up properly and I am also able to upload 'the out-of-box_aop' as well as the 'people_tracking' example on the board (through serial port) successfully. But it seems the chip does not initiated properly, i.e., it does not return the 'Debug: mmWave Control Initialization was successful' message. While uploading the same code on the TI 6843EVAL board I am getting the successful initialisation message.
I have checked all the supply pins. Also the SOP pins have changed to the 'Debug' mode after writing the firmware.
Any help or hint about the potential issue is really appreciated.
UPDATE: I assumed it might because of the HSI crystal, so I have deactivated all the functions/initialisations in the code and just configured GPIO2 as an output to toggle an LED. The code works well on the TI eval board but not on the custom board. It is obvious that the core does not initiate. Any help is appreciated.
