TMS570LS0714: TMS570LS0714

Raphael_w

Part Number: TMS570LS0714

Hi TI Team,

I would like to program the TMS570LS0714 via JTAG by using our own programmer.

I used the CCS to build a bootloader and wrote the bootloader to sram of TMS570LS0714. I used the bootloader to call the API to program Flash of TMS570LS0714.

But sometimes I got the worng data from sram. I tried to halt the device to get the sram data to see if I could get the correct data, but sometimes it faild.

Yes, you should need to load the bootloader code via JTAG, once you load the bootloader then you can give your application binary to the bootloader through corresponding bootloader peripheral like UART, CAN and Ethernet etc.

Thanks & regards,
