Net-snmp update 748 0
Started by Daniel Dodge
Has anyone upgraded to a later version of net-snmp (version > 5.5)
Could anyone provide an example or particularly and net-snmp.spec
I think this is as easy as finding an updated *.gz file and then creating a hash file for it. Then just updating the *.spec file. It has been a while since I worked with Ltib so I might not be a hundred percent clear on this.
Does this cause various other libraries to need updating as well
We believe the old version of net-snmp (5...

Mainstream DM37x Linux 3227 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...

How to enable NEON SIMD via compiler 1284 1

We are using the torpedo Linux BSP v2.4.4, and arm-none-linux-gnueabi-g (Sourcery CodeBench Lite 2011.09-70) v4.6.1

Modern (4.2) Kernels and I2C1 @ 2.6MHz 1268 0
Started by Adam Ford
Users of the 4.2 kernels should consider one of two patches for the I2C1 bus. The pin muxing was not setup properly when the board was initially ported. Users trying to use the I2C1 bus at 2.6MHz should use one of the following patches:
Torpedo: https://patchwork.kernel.org/patch/10184763/
SOM-LV: https://patchwork.kernel.org/patch/10187657/
These patches configure the pinmux for I2C1 to disable the internal pull-up resistor and utilize t...

Kernel 4.14.y WiFi Bug on Torpedo Wireless 1043 1
Started by Adam Ford
People using Kernel 4.14.y from kernel.org should be aware there is a bug that misconifgures the MMC3 devices, so the WiFi driver doesn&39;t communicate properly.
A fix was later introduced, and a request has been made to back-port this driver.
In the meantime, users of 4.14 through 4.14.14 should use the patch located:

Linux 4.10-RC and Damage to DM37 Torpedo 1564 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...

Enable WiFi in Mainstream Linux (Torpedo Wireless) 3527 13
Started by Adam Ford
When building the kernel, make sure the following is enabled in the menuconfig:
Networking Support ---> Wireless ---> nl80211 testmode command
If not, the WiFi may not scan.
From there, you'll need to copy the NVS file from the 3.0.x kernel BSP.
The stock BSP has 3 NVS files. That driver have been modified to identify the chip type and load the corresponding driver. Since the mainline kernel does not have this feature, you'll have to manually copy the nvs file.

readwrite access to NTFS formatted SD card 1536 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...
