TMS570LS3137: About Ethernet upgrade bootLoader in TMS570LS3137 chip

Hi team,

Here's an issue from the customer may need your help:

The customer have a sample program about BootLoader (Hercules_Ethernet_Bootloader). They want to apply it to the TMS570LS3137 chip and upgrade app via Ethernet. Following the example, they've managed to upload a program to light up the LEDs via TFTP and everything went well until then.

But when they wanted to use lwip in app program, the app that contains lwip related code cannot be executed after being uploaded.

Then they tried simple printf, malloc, etc. and found that apps containing dynamically allocated memory or calling interrupts were not executed correctly (these programs can be run correctly when burned directly on the chip using uniflash).

The following files are bootloader and sample programs they used:

Hercules_Ethernet_Bootloader.zip

app_test.zip

Could you help check this case? Thanks.

Best Regards,

Cherry

Hi Cherry,

From your message, the ethernet bootloader works well and the application image is loaded to flash. The issue is that the application image doesn't work, right?

This is the memory map in your linker cmd file:

MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x0017FFE0
FLASH1 (RX) : origin=0x001A0000 length=0x00180000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0003EB00

/* USER CODE BEGIN (2) */
/* USER CODE END */
}

you should use application start address here.

For example:

MEMORY
{
/* USER CODE BEGIN (2) */
VECTORS (X) : origin=0x00200020 length=0x00000020
FLASH_CODE (RX) : origin=0x00200040 length=0x8000 - 0x40 fill=0xFFFFFFFF /*sector 4/5*/
FLASH0 (RX) : origin=0x00028000 length=0x00200000 - 0x28000

Where 0x200020 is start address of the application image
