RE: Download - Added by Michael Williamson over 14 years ago

Hello,

The CLUB is not used for downloading to the MityDSP-L138F and/or MityARM-1808 processors. These processors utilize the das U-Boot application running on an ARM core as the main bootloader and boot-up mechanism. The CLUB is intended only for processors that do not support running U-Boot (i.e., DSP only CPUs not including an ARM core such as the MityDSP-6711, MityDSP-6455, and MityDSP-6748). The version of U-Boot provided with the factory configured MityDSP-L138 or MityARM-1808 is capable of downloading files with several machinisms, including (but not limited to):

  • Serial Kermit Download
  • tftp via ethernet
  • nfs copy/load via ethernet
  • bootp via ethernet

USB thumbdrive support, Serial ATA support, and MMC card support are also possible, but is not included with the u-Boot build provided in the factory configuration.

U-Boot is a text/command line interface that runs on UART-1 of the MityDSP-L138 OMAP processor at 115,200 baud 8 bits no parity (no flow control). From linux, you'll need to use a terminal program like putty and connect through a serial port (e.g., /dev/ttyS1 or /dev/ttyUSB0 for a USB to serial adaptor such as a keyspan unit). Once connected, you can issue download commands via the methods listed above. There is a very good user's manual that includes tips for using das U-Boot with a linux host for file download at the U-Boot main site. Chapter 4 covers setting up NFS, TFTP, and serial ports for linux. Chapter 5 covers the basic commands for U-Boot. There is a "help" as part of the interface.

I would recommend setting up a tftp server to initial downloading. Once you have determined how you want to program your software into the SOM, you can script your download session.

It would seem reasonable that a GUI application could be written to wrap the U-Boot console interaction, but we don't have anything like that available today. While U-Boot is a text based interface, I think you'll find it's quite flexible/powerful.

Dennis -

Just like to add that if all you need to do is download an application to the filesystem in NAND flash, and Linux is already up (on the target), there are a number of other options. These would include standard FTP (would have to make sure the FTP server is installed on the target and running), NFS copy, or the scp command from your host system.

Took me a while...FYI be sure to tell anyone else 2 stop bits, my set up defaulted to 1.
