   Hi,

   I'm new using a maple-like device, but I do have experience in embedded design.
   I'm using maple-ide-v0.0.12, on Opensuse 12.1 32bit. From the start I installed the udev-rules file and made myself member of group plugdev.
   When I try to upload my application to the device, I need to reset it, just on time for the ide to find the device. I'm wondering if this is how it should be done.
   If I dump the program to flash, I need to unplug the usb, and then plug it back in to start the application. Working in RAM works better, then after the program is uploaded, it starts fine. Unfortunatly, my application is already too big to work in RAM.

   Another thing, I think related to the first problem : I can't access serialUSB. The ide has greyed out the menu-item to select the serial port. If I manually modify the config-file to use /dev/ttyACM0 the monitor still complains about not finding the port.
   /dev/ttyACM0 is in group dialup, so I added myself in that group and logged in again. This does not help.

   Any suggestions how I can solve my problems ?

   TIA,
   Regards,
   Koenraad Lelong.

   Hi,

   Thanks for your response.
   Unfortunately the only thing I see by reading the text is that I indeed have a problem. According to the text, the IDE should reset the board, but as far as I can tell it does not. I think it's because /dev/ttyACM0 does not work for me. So how do I fix that ? I can't probe that DTR pin, is it ?

   Maybe I'm misreading something ? English is not my native language.
   Maybe I should try a new bootloader, to be certain I have the latest ?

   Koenraad.
