Part Number: AM3352
Hello All,
We have a new AM3352 based board who's design is highly influenced by Beaglebone. As part of the board bring up, when we connect our board through UART0 to console, we see junk characters ("���������������") instead of "CCCCC".
The rate at which the junk characters are being printed on the console is the same rate at which "CCCCC" would be printed. I connected scope on the UART0_TX pin and I can see the square waveform signals on the scope. I have compared the waveform with the normal "CCC" waveform and found out that, the width of the square wave from our (non working) board is SMALLER than of the working one. I also tried connecting our board using TI XDS200 JTAG connector and it did connected fine. When I run the debugging and check the diassembly, the program counter normally stays around 0x233XX which is in the range 0x20000-0x2C000 (ie, somewhere in ROM code). Hence I believe the console/UART is broken somewhere.
I am trying to figure out what causes the junk character on the console, so that I can further continue the bring up process. Any test case or solution to this issue will be highly appreciated.
Thanks,
Divyeshkumar
