TMS320F2800135: Flash Programming with SCI Bootmode

Hi Matt,

I tried increasing it from 38.400 but the connection is lost at 40000 and I cannot program the flash.

Hi,

Can you try using a different USB cable? I was able to successfully use the flash programmer at 115,200 with F2800137.

Hi,

Can you share your setup? I have universal a programmer that I did myself and I entegreted this aplication (C2000Ware_x_xx_xx_xx > utilities > flash_programmers > serial_flash_programmer).in my system .  As I said before,there was no comunication over 38400. In reference manual I found at below part .

Hi,

Yes, the SCI max baud rate is determined by LSPCLK/16, which even at the LSPCLK minimum frequency of 2 MHz the device should be able to support 115,200 bps.

I am using the LAUNCHXL-F2800137 with the on-board XDS110 JTAG debugger serial interface. What serial interface are you using?

Hi ,

I use serial interface UART .

When we try to flash a card with bootmode via UART for the first time, do we need to make any configuration in the kernel file to increase the baudrate? As I said before, the connection is lost above 38400 and the processor cannot be programmed.

Hi,

By default, the kernel should be able to handle the SCI baud rate configuration with the auto-baud detection. Can you link what serial interface UART part you're using?

Best,

Matt
