TMS570LS3137: TMS570LS3137

Hi,

The TMS570 devices don't have ROM bootloader. TMS570 MCUs have internal flash, and you can program your own bootloader to flash.

TI provides example project of bootloaders: UART, DCAN, SPI, and Ethernet.

Hi Wang,

Thank you. I have one more doubt on JTAG lines. Can we use Power reference instead of GND for JTAG lines.

What is the power reference? Can you please give me more details?

Power reference means power plane as a reference for signals.

For a scenario, initially the signal routed on external layer and GND plane as a reference after the signal traverse inner layer for the portion of signal which is routed in inner layer is referred with power plane. Is this ok.
