Q about TMS570LC4357 flash programing with UART

Hi Charles

Thanks a lot. According to what you said and the spna193.pdf , i am trying to port the project to LC4357 which is used for  LS31x device. 

I got some problems. Here attachment is my project in ccsv6.2.

1. in flash_definitons.h file, how to define flash sectors? The  flash memery in lc4357 is larger than lsxx.

2. define SYS_CLK_FREQ as 300 is right?

3. which F021 api lib is for lc4357?F021_API_CortextR4_BE or F021_API_CortexR4_L2FMC_V3D16.

4. here is my cmd file.  Is that right?

MEMORY
{

VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH_API (RX) : origin=0x00000020 length=0x000014E0

5. I got bad function location which are in bl_flash.c. like this :

I will very appreciate for your help.

Hi Jinus,

 1. You can find the sector information in the datasheet. Below is a snippet.

  2. I think you need to use 150MHz instead. The 300MHz is for the CPU (GCLK) clock. However, the flash controller operates at half the frequency HCLK).

  3. You should use F021_API_CortexR4_L2FMC_V3D16.lib or F021_API_CortexR4_L2FMC.lib

  4. You need to replace with the correct library in your command file as indicated in 3) above.

Hi Charles,

Thanks for your help, I have successful run uart bootloader and send bin file to lc4357. But, I've had some other problems.

1. Very time start user app form bootloader should goes to _c_int00(In user app, created by HalCogen 4.05). It seems that some configrations stop reinit cpu that will cause cpu Abort. If directly goes to main without doing cpu initialization in _c_int00, the app runs good without any problems.How to solve it?

2. How to create bin file that can download to interalflash directlly via uart port? I now using the tool hex470.exe. The hex file created by ccsv6 (Settings shows blow) is right?

Thanks!

Jinus.

Hi Charles,

Thanks very much. The bootloader for lc4357 runs well after using the bin file created by ccsv6.  

Thanks again for your support.

Regards.
