Serial Download
The following example demonstrates a serial download via the ymodem protocol:
The KTT20/pITX board is connected to a desktop computer with a suitable terminal program (e.g. Hyper-
Terminal or TeraTerm). The file size of
wvga.kdb amounts 81 bytes.
For downloading the file into memory type the following standard U-Boot command line
loady
Now U-Boot waits for reply. User input to the desktop terminal program starts the download session. After
the download of
wvga.kdb ends you can control the result with the md command (the memory address
0x408000 is fixed)
md.b 408000 80
Now you can load the memory content into the EEPROM. Type the new KONTRON U-Boot command
writedid 408000 51
The 'count' respectively the size argument is a very important parameter. Do not use another value as the
file size of your DisplayID
TM file.
