C5502 uart bootload

Hi,

First of all, have set your CLKIN correctly so that the baud rate is matching to 57600?

The hex55 configuration should be like this:

−boot ;option to create a boot table

−v5510:2 ;use C55x boot table format for TMS320VC5502

−serial8 ;UART (8-bit)

−b ;desired output format is binary format : change to your required format option

−o my_app.hex ;specify the output filename

-e entry_point_address ; your entry point

-map file_name  ; output map file name

my_app.out ;specify the input file

Regards,

Hyun

Hyun,

Yes, I use a 15MHz crystal as a CLKIN on by board and when I send a byte the echo is the same that I send. So I believe that baudrate is not the problem.

I use the same hex55 config you suggest. 

Anybody could have another suggestion?

Thanks

Hi,

Where is "stop" happening? Is it in your PC side or DSP side?

Hyun,

The echo stops in DSP side.... It not reply the byte that I send....

Hi,

Have your code (.out) verified with a emulator or booting differently (not UART)?

Have your PC program used before for UART download? I want to know where it went wrong.

Regards.

Hyun,

Yes, I´ve verified my code with JTAG and EEPROM boot. It´s a basic blinking led firmware.

I power on the board with UART bootload mode selected without a jtag connection. So, PC program are not used before UART download.

Thanks

Hyun,

I found out that the error was in my project. This vector isr section wasn´t right and when I tried to download the code to address pointed the bootloader crash.

So, I declare the section, build the project and download it witout a problem.

Thanks for your reply.
