17 Replies and 2276 Views Mainstream DM37x Linux  2276  17 Started by  Adam Ford A beta BSP has been released for the DM3730 / AM3703 Torpedo and Torpedo Wireless products with mainstream Linux 4.4.x kernel.   This BSP has not been fully tested, not all features on the baseboard are enabled, but it can provide a nice starting point for users wishing to have a newer kernel and libraries.  This BSP uses vanilla kernel with a device tree for the Torpedo Wireless which can be modified to support the non-wireless Torpedo.  Kernel 4.4 was selected because of its l...

0 Replies and 818 Views Linux 4.10-RC and Damage to DM37 Torpedo  818  0 Started by  Adam Ford There was a patch to the Linux Kernel in the 4.10-RC series that appears to break the Smart Reflex.  I have worked with the author of that patch and he has developed a fix.   During the course of testing, the Torpedo Wireless SOM I was using was damaged.  It is unclear whether or not the damage was due to the software, but since Smartreflex is involved with setting the processor voltage, I would suggest people say clear of Kernel 4.10 -RC series until the fix has been appl...

3 Replies and 990 Views readwrite access to NTFS formatted SD card  990  3 Started by  Rob Birkner Hello, I'm trying to set up our Torpedo so that we can create large files (>2GB) on an SD card formatted so that it can be read later on windows systems.  It seems that a volume formatted as NTFS or exFat is needed to support that seamlessly.  It looks like the BSP supports NTFS, but not exFat. I've configured ltib to include the NTFS and NTFS rw driver(s) and formatted the SD card partition as NTFS, and can mount the partition so that it appears to be readwrite, but I still can't w...
