2.2 Serial Boot and Flash Loading Utility

This package contains a set of utilities running from the command-line on Windows for flashing the NAND, NOR, and serial peripheral interface (SPI) Flash of the OMAP-L138 EVM via the serial port.

The latest source code and binaries can be downloaded from https://www.ti.com/lit/zip/spracm8.

The Serial Boot and Flash Loading Utility (which offers the same functionality as a previous program called DVFlasher) executable is called sfh_OMAP-L138.exe.

These programs each encapsulate a distinct binary UBL that is transferred via the universal asynchronous receiver/transmitter (UART). This implies that the chip must be operating in the UART boot mode, showing the BOOTME prompt.

Note: The assumption is made that the UART of the device operates at 115200, 8N1. If the oscillator used with the device does not match the one used on the EVM (on a custom platform), the baud rate assumption may be incorrect.
