NAME

dvnixload - UBL and Application flasher for TI DaVinci platforms.

SYNOPSIS

dvnixload [OPTION]... UBL APPLICATION

DESCRIPTION

dvnixload is a utility to program a UBL (first stage bootloader) and an application (2nd stage bootloader, ex. U-Boot) in NAND flash memory over the serial port.

Both files UBL and APPLICATION are mandatory and must be in the ELF format. APPLICATION is typically U-Boot. You don't have to manually specify the entry point for the UBL or APPLICATION, everything is extracted automatically from the ELF headers.

The program will convert the ELF files into binary format (for the RBL) and S-record format (for the UBL). But the UBL source code must be modified somewhat because the original UBL expected to see the starting load address in the S7 record inside the S-record file, but the S7 record is supposed to hold the entry point according to the Motorola S-record specification, and this is what the standard GNU tools like objcopy will do (objcopy is called by dvnixload).

OPTIONS

-b, --baudrate=BAUDRATE

Serial port baud rate. Default is 115200 bps

-d, --debug=LEVEL

Produce verbose debugging output. Valid levels are:

0: display only error messages
1: display warnings (default)
2: display info messages
3: display debug messages
4: increase verbosity of debug messages
5: increase verbosity of debug messages

-p, --port=PORT

Serial port device. Here are some examples of valid devices:

/dev/ttyS0: First serial port (default)
/dev/ttyS1: Second serial port
/dev/ttyUSB0: First USB serial port

-?, --help

Give this help list

--usage

Give a short usage message

-V, --version

Print program version

ENVIRONMENT VARIABLES

The program will honor the value of the CROSS_COMPILE environment variable when calling external programs (objdump, objcopy, readelf). The default value is set to "arm-linux-"

LIMITATIONS

dvnixload currently support only writing to NAND flash.
