- Mike,
Thanks for the quick response. Monday is Ok, I'll get the QNX development environment installed in the meantime.
Regards,
Rob - MW 02:59 PM Software Development: RE: QNX
- Hi Mr. Gillis,
We do have a QNX port and a BSP package, but we haven't migrated it to our external support site yet. Our resident QNX "expert" is out of the office until Monday. He would really be the best person to ensure that the ... - Hello,
I am trying to evaluate QNX for our MityDSP-L138, and the apps engineer indicated that there is a custom BSP created by Critical Link for this module. I can't seem to find it on the Wiki, can someone point me to the right loca...

Thanks for the info.
Here is what I need to do.
I have 4 different work blocks doing some stuff and sharing some stuff
First block
Must fit into 20uS.
In this time, it must

- Hi Simon,
The architecture used for these processors is the "davinci" architecture. The information you want to look at is primarily in the arch/arm/mach-davinci folder, though some of the drivers (like spi and i2c) are located in dr...

- Hey,
I would like to be able to setup the hardware timers of the AM1808 inside the OMAP so one of my function os called periodically based on the timer interrupt. I read a bit about arch/mach-XXXX stuff and from what I got, all the pl... - JM 01:48 PM Software Development: RE: Loading a New Kernal

I think the kernal they have compiled replaces some of your drivers with Ciann... - TI 01:39 PM Software Development: RE: Loading a New Kernal

Updating Software Images on the MityDSP-L138¶
This topic outlines what you need to do to update the FLASH (SPI, or NAND) images on a MityDSP-L138. This topic assumes... - Sorry if this is redundant but my software guys are not available today and I am stuck. I need to load the Cianna kernal on my hardware in order to debug the LCD. I am on a windows system and the Ethernet does ping from uboot but not ...

- ST 07:21 PM Software Development: RE: ARM peripherals
- Hey Mike,
I'm not sure I follow you when you say to check out the linux source code to see which drivers are already available... Is it stuff under linux-davinci the linux source code or stuff under angstrom?
I don't think I need ... - MW 06:35 PM Software Development: RE: ARM peripherals
- Well,
There are two paths for hardware access. Many of the devices (LCD, some SPI, uarts, etc.) have corresponding devices drivers in linux already, so you would access for example UARTS by opening /dev/ttyS0 or /dev/ttyS1, etc. The... - Hi,
I got my setup working now... I can debug a hello world application, trace in it using gdbserver etc... Now, I'm wondering how to access the hardware of the AM1808... spi, uart, timers, ios, interrupts, etc... Is there a good plac... - ST 02:09 PM Software Development: RE: Getting started
- Hi again
Is there a release note somewhere about the Release 2010-10-12? I think the VirtualBox image I had on my dvd contains stuff from Release-2010-05 so I'm wondering if it's a good idea to update everything to october 2010 stuf... - MW 01:17 PM Software Development: RE: Getting started
- Hi Simon,
Yes, you are right, you probably won't need CCS or the Emulator (except, perhaps for the PRU...).
The PRU user-space driver access for linux is fairly new, and not yet included in the kernel from Critical Link yet, but I ... - ST 10:42 AM Software Development: RE: Getting started
- Hi Mike,
Thanks for your fast reply!
For my project, I will probably only use the ARM side. In fact, I wanted a MityARM but there were only MityDSPs available. Since the AM1808 is in the OMAP it's no big deal cause I can do the exa... - MW 09:35 AM Software Development: RE: Getting started
- Hi Simon,
For software development, there are really two distinct development paths / tools. One is for the ARM, which involves a port of gcc and (for most folks) eclipse and gdb via gdbserver. At the moment, the primary OS supporte... - Hey everyone,
I just received my MityDSP-L138 and I'm kinda lost about where to start with it. Is there some documents explaining some basic stuff to get started? I have CCS 4.1 installed and a XDS100USB to debug. I'm just wondering w...

- WF 01:39 PM Software Development: RE: Audio help needed
- This helps point the way. I'll let you know when I have additional questions.
Looks like I should check out both the McASP and AIC3 modules to see how they can be adapted to what I'm trying to do. Thanks. - MW 08:02 AM Software Development: RE: Audio help needed
- The MityDSP-L138 (really, the OMAP-L138 or AM1808) uses (primarily) the McASP to support audio. McASP drivers are included in the linux kernel. The linux kernel will also support audio over I2S and SPI devices, but I do not have experi...
- WF 12:37 AM Software Development: RE: Audio help needed
- We're at the point where we are now developing audio code for our app. What is the status of the audio drivers for the MityDSP? Even if it's not complete, we could use some example code to help speed our configuration efforts. I have a T...

- DV 08:52 PM Software Development: RE: LCD/Display questions
- We are looking at the user space solution. My hardware person says I'm wrong, he has attached the device I need to access to spi1.
- MW 08:22 PM Software Development: RE: LCD/Display questions
- On the current industrial I/O kernel configuration, SPI0 is disabled as pins associated with it are used for the MII interface. I assume you are using a custom host board solution.
Do you need access via ARM? or DSP?
If by ARM, y... - DV 08:02 PM Software Development: RE: LCD/Display questions
- I need to access spi0. It appears something related to it is compiled into the kernel (devices-da8xx.c/.o). But I don't see a mechanism on the running platform to load/access the device.

- WF 07:31 PM Software Development: RE: LCD/Display questions
- Great. Sounds like for our purposes we probably don't need these commands, since we're connecting the LCD through the FPGA. We'll follow up further if that turns out not to be the case.
- MW 10:49 AM Software Development: RE: LCD/Display questions
- The "TFP410":http://focus.ti.com/docs/prod/folders/print/tfp410.html DVI interface chip is located at address 0x38 on the i2c bus. The link provided at TI allows access to the data sheet for the part, which contains a full address map f...

- DV 09:25 PM Software Development: RE: LCD/Display questions
- In the wiki entry on setting up the LCD, the i2cset command was used to set a couple addresses in chip 0x38. Did that only apply to the DVI and not the LCD? If it applies to the LCD, is there documentation on what those addresses on the ...
- DV 02:47 PM Software Development: RE: Boot failure
- That worked. We are up and running.
A little search of the kernel source tree shows that in arch/arm/configs most of the "defconfig" files have CONFIG_CMDLINE set to a string that includes "rootfstype=jffs2", but the mityomapl138_defcon... - MW 01:52 PM Software Development: RE: Boot failure

It looks like the bootargs environment variable in u-Boot has become corrupted.

- WF 03:30 PM Software Development: RE: LCD/Display questions
- Thanks. This is the first of the steps we needed to understand.
I don't think we'll need help with the hardware itself; we have a guy here who's designing and building it, and as long as we can make the da8xx structures and 138 tables... - MW 03:06 PM Software Development: RE: LCD/Display questions
- Hi all,
If you have designed your own hardware using a new LCD, I'm afraid you're going to be on your own to get it functioning (unless you can provide schematics, your FPGA code, and some hardware for us to support you with). I can,... - WF 02:49 PM Software Development: RE: LCD/Display questions
- We're in need of some information on this item because our primary assignment now is to implement our LCD functionality in the unit. When can we expect to receive feedback on this issue? Thanks.

- WF 07:08 PM Software Development: RE: LCD/Display questions
- Related Notes: just so you know, we have an FPGA binary which supports our new LCD panel, and it maps the memory for the LCD to the same location that's used for the current two Critical Link supported devices. So we'll be using our own ...
- DV 06:39 PM Software Development: RE: LCD/Display questions
- The wiki lists vga_640x480 and Sharp_LQ035Q7DH06 as Displays that are known. The new version of the board we have been given has a
COM57H5M06XRC (TFT-LCD) attached. What should I set for "LCD Panel" in the UBoot?

- JM 11:00 AM FPGA Development: RE: TLK100 Ethernet
- Mike,
FYI It was the bias resistor. There was a type in the BOM and a 49.9K was installed instead of a 4.99K. Once I replaced this everything worked fine.
