Recovering uMon

You may need to recover your MicroMonitor image (due to Flash corruption) or if your board stops booting due to problems in the TFS (~TinyFileSystem?) of uMon. One technique is to configure a uMon to run from RAM, use an emulator to load it to the CSB350, then run it and perform maintenance to the boot filesystem, etc.

See (http://www.microcross.com/app-tutorial-recover-umon.pdf) for instructions

  • now use these files to recover your CSB350 uMon image.

Additional information on MicroMonitor as well as the source code can be obtained from (http://www.microcross.com/html/micromonitor.html) Pre-Built uMon With TFSAUTOBOOTABORTABLE Enabled A link to a pre-built uMon for the CSB350 with TFSAUTOBOOTABORTABLE as per MicroMonitor sec. 13.7.1. can be obtained here: http://www.ngit.com/blog/csb350/umon-082604-bv.zip --BogdanVacaliuc?
