Recover Torpedo Wireless SOM 1225 3
Started by Joshua Pagnotta
Hi,
We have a SOM installed in our device which doesn&39;t appear to be outputing anything over its console UART on power on. The last working time this SOM was booted a nand erase.chip was performed in u-boot and after that inserting a boot SD card (made with the mkLogicFATCard.sh) with MLO and u-boot files on it won&39;t boot at all. Nothing prints on the UART console. I tried putting the files from 1028255 DM37x SOM Recover NAND flash procedure in product downloads on a bo...

PMIC RTC Security 1121 1
Started by Alex Roberts
Looking at the schematics, MSecure signal on the TPS65950 PMIC is tied high to 1.8V (VIO_1V8). I am assuming this puts the PMIC in secure, preventing my ability write to the real-time clock registers via I2C.
A quick test in LOSH shows writing the year, for example, does not update the register value. From the TPS65950 TRM, YEARS_REG is in the 0x4B group and the physical address is 0x21

Started by Derek Valleroy
Hello,
We have an application on the DM3730 that uses the OTG host. We now have a need to implement a suspend state. Is there any example code or any application notes that cover this Any gotchas that we should know about

DM3730 Torpedo 1433 5
Started by Greg Durant
I&39;ve a design with the Torpedo (dm3730) in an embedded (SOM interfaced to a USB/Eth bridge device on custom board) implementation. I&39;m unable to get the SOM to recognize the USB/Eth bridge device physically (USB data lines) interfaced to the SOM&39;s USB OTG port. Additionally, the USB_ID pin is grounded on the custom card to indicate to the SOM it is to be the host. Can you add any insight into what the problem would be I&39;ve since noticed this specific note in the Torpedo HW Speci...

libusb and mainstream kernel 1317 4
Started by Brian Frohlich
Hi,
I am trying to port code from linux 3.xx to the mainstream 4.4.9. &39;lsusb&39; shows me the the device I am interested in, but I cannot write or read. The application for communicating with the device uses libusb and worked fine in linux 3.xx and recompiled without a problem.
Anyone been able to communicate with their usb device on DM37xx with the mainstream release
Thanks.

Bare Metal McBSP issue 1148 2
Started by Mark Gregory
I am currently running McBSP2 to interface to an ADC using the SRG to generate the clock and frame sync and receive into DR. All signals look to have appropriate amplitudes and timing except for the frame sync. Frame sync is ~.9V half of what I expect (1.8V).
After reviewing all of the SOM and EVM board schematics it looks like there are no connections to the McBSP2 module except to the TPS65950 power module. The SOM schematic specifies that if there are any codecs or external mcbsp mod...

uP_D8 thru uP_D14 data lines as GPIOs 1173 1
Started by Deleted User
We would like to use the signals labeled uP_D8 thru uP-D14 as GPIOs They are labeled as either processor data lines, or GPIO on the schematic.
How are these lines configured as GPIO (the same as other GPIOs via /sys/class/gpio system calls) and what will prevent them from toggling during boot-time until configured as GPIOs

Unable to flash Mainstream Linux RAMdisk/ubifs to NAND 1585 5

Hello All,
I have been using the Beta Mainstream Linux VM to try and flash my DM3730 Torpedo SOM. I have successfully booted it from an SD card with the EXT3 rootfs, but I&39;m having trouble both booting from RAMdisk on an SD card, and then (since that doesn&39;t work), I can&39;t get to the part where I would mount/add the ubifs into NAND. When I go to boot from RAMdisk, kernel seems to hang on the &39;Starting Kernel...&39; message. I&39;m not getting any more output from the debug U...

TPS65950 (PMIC) Backup Battery Voltage giving unexpected readings 1358 3
Started by John Huang
I&39;ll state the obvious first, in case anyone needs some background.
I am working with the Torpedo DM3730 SOM which has an integrated PMIC (Tps65950). According to the PMIC, we can stick a coin cell to the backup battery to keep the RTC running. Then the voltage of the coin cell can be read using MADC CH9.
In the Linux BSP User Guide, it offers a script to do exactly just this. I have ran the script and I am able to read the ADC values for CH9 and the script also convert...

DM3730-SOM: Configuration of I2C1 to communicate to PMIC. 1758 6
Started by John Huang
I am working on the DM3730 Torpedo SOM using the provided Linux 2.4-4 BSP. I understand the I2C-1 bus coming out of the DM3730 IC goes directly to the TPS65950 (PMIC) as the main form of communication. To send I2C data and request over this bus, I am relying on the i2c-dev.h bus driver and the use of open/ioctl/read calls.
Using these mechanisms, I have been successfully at talking to multiple external i2c devices through the I2C-3 bus. In fact, I&39;ve hooked up a Logic An...

hi,
I booted the omap3 torpedo som from the mainline kernel (using logicpd&39;s dts and defconfig).
In the kernel boot log the nand chip is being recognized without errors and 5 ofpart partitions are found on the device.
When i&39;m trying to write to the chip i get: error 5:(input/output error).
Has anyone encountered this problem

MUSB Peripheral with Mainstream Linux 1704 9

I&39;m using a 4.8.6 kernel with my DM3730 SOM and am trying to use it as a USB peripheral. I am able to successfully load the module, connect the USB cable, and load the driver on a Windows 7 host. The device functions perfectly for a while but about a minute after connecting to the host the USB gadget driver seems to go into a suspended state which causes the device to become unrecognized by the host. I have tried this with the g_serial and g_mass_storage gadgets and they both produce similar...
