Bootloader error for TMS570LS31x

Hello Wooseung,

I have forwarded your question to our bootloader expert. He should reply to your post soon. In the mean time, it might be helpful if you could post your code and let us know which device you are using.

Hello Wooseung,

How do you create the raw binary file (image file)? The project I posted uses Release mode, if you use it as Debug mode, the location of API obi files should be redfined in cmd file.

Attached is the image file I used for testing. After the image is uploaded to flash successfully, the execution should jump to your application. You will see the LED flashing on HDK.

Thanks for your reply, QJ. 

I've done test bootloader.

The reason that ymodem doesn't work is bl_flash. 

So, I modified bl_flash, bl_link.cmd

I used bl_flash.c file that u provided with F021 API. And, I modified bl_link.cmd little bit. 

but, I'm still curious about "flash_bank[bk].numOfSectors". I can't find the variable. 

So, I just cut the line. and then it works well.

Thank you for your helping.

This is the bl_link.cmd I modified.

QJ,

If you don't mind can I get the blinky application source that could be the blinky binary file. 

I've got this source, but I think the source is different with the binary file u gave me.

Thanks a lot.

Hi Wooseung,

You can use the same project. The only change is the code load address which is defined in cmd file. I highlighted the changes:

/*----------------------------------------------------------------------------*/

/* Linker Settings */

--retain=

"*(.intvecs)"

-heap 0x800

/*----------------------------------------------------------------------------*/

/* Memory Map */

MEMORY

{

VECTORS (X) : origin=0x00020000 length=0x00000020

FLASH0 (RX) : origin=0x00020020 length=0x0017FFE0

STACKS (RW) : origin=0x08000000 length=0x00001300

RAM (RW) : origin=0x08001300 length=0x0003ED00

}

Thanks QJ.

I've solved the problems.

It works well now.
