jtag -i Identify the flash part used

This option tries to identify the part number of the Flash EEPROM. Currently supported parts are 28F160F3B, 28F320J3A, 28F128J3A, 28F320C3B, and 28F320S3, though not all have been tested. It should be relatively easy to add new parts.

jtag -f Generate the appropriate signals to program a flash.

This option is rarely used, since we normally program the flash through the minidebug software.

jtag -c Download code to the mini and main instruction cache.

This option is used to load a file into the instruction cache. Usually -x, -e, -or -d option is used to load minidebug. The -d option just loads minidebug. The -x option then proceed to dowload a file over the serial port using xmodem. The -e option dowloads a file using ethernet (wireless and wired support.) The -ssid option can be used to specify a wireless essid value to pass to minidebug.

jtag -s Terminal emulator option.

The parallel port is still searched because [Ctrl A] B can be used to send a JTAG break and attempt to return control to minidebug.

jtag -N Burn the entire flash.

This option can be used to burn a flash for the first time.

It first downloads the file mdebug to ram address A1800000. Then it executes an ethernet download of the file totalflash.

If successful, it then burns the flash using the minidebug(mdebug) command BALL (burn all).
