  • Forum Post: USB Host controller

    manuel
    Hi, Did anyone got the USB interface of the OMAP3503 EVM working with Linux ? I want to connect a USB sound card, and it just does nothing. I do not get a USB event when I plug in any USB device. Just nothing happens. The USB Host driver is built in, detects one HUB Root, but thats it. As far as I understand...

    Hi, thanks for the reply. I already had considered all the details posted so far. I also checked the cable if the ID pin was actually connected to ground, and it was as it should be. So the cable is not broken or something like that. Im also using a powered HUB. When I do a "cat /proc/driver/musb_hdrc...

    Hi everyone, It turned out that my OMAP35x board was broken. I tried another different board one, and USB devices are detected just fine. But, it does not work either. Either with the original SDK 1.0.0 default kernel or custom kernel with different USB driver settings (experimental code for better transaction...

    Hi, thanks for replying, but I have been using ALSA for several years (as user, driver and application developer), and I have never had any problems with multichannel. I also have other ARM based systems working just fine with the very same audio cards in multichannel mode. I will try using another USB...

    Good to know that you are familiar with the ALSA infrastructure quite a bit. We had an issue with the usbaudio.c code in "sound/usb" directory were the USB flags were not correctly updated. This lead to random oops after recording stopped. We corrected the issue by correctly updating the...

    Hi, Thanks for the information. I did some googling about that. Does this problem show up under any circumstance or only if I request explicitly the ASYNC mehtod ? The error message that is supposed to reveal this problem seems to be "file descriptor in wrong state" or something like that....

  • Forum Post: Re: Can anyone tell me how to generate strace utility from SDK?

    ddompe
    Ajit, You can compile this from open source by grabbing the strace packages from source forge and applying the patches required to support ARM EABI (not sure if they are already merged with latest strace releases). RidgeRun offers an Developer SDK for OMAP35x already that includes strace, ltrace...

    Hi, From some TI webcast we have gather that TI SDK team is moving towards having the next release based on Git kernel. Keep in mind that Git is a moving target and therefore is important to perform an feature freeze and stabilization work on it to create an SDK. Another issue to consider is the drivers...

    Hi, Hit post too soon. To answer the specific question, if you want to do the port yourself is better to use the omap git kernel at source.mvista.com. It has a decent support for OMAP35x EVM. Regards, Diego

    Juan Gonzales
    Sorry, I was focusing too much on the audio portion of the issue and blocked out the USB. Based on the log you sent earlier, it appears the USB device is not being recognized; therefore this is not an ALSA/audio issue but rather a USB device interface issue. I agree ALSA supports multiple channels...

    Hi, Arm runs Linux (montavista is just a version of Linux). They communicate using DSPLink, which is an API for inter-processor communication that is available for Linux, and for DSPBios. Regards, Diego Dompe RidgeRun Engineering

    Hi, We use the T32(lauterbach), which has graphic interface available for Windows and Unix (Linux). It doesn't provide IDE features like build-deploy-debug, but instead a debugger interface with symbolic debug support, and it does have the most powerful debugging interface for embedded Linux over...

    ddompe
    Twebb, Lauterbach has support for several platforms and configurations, I *think* it is the Trace32-ICE what you need. T32 ETM support is optional (requires an separate license for the ETM support), so the jtag lines are enough (on the other side I think the OMAP has an ETB in the scan chain, so you...

    I have a clarifying question for you, just so that I am clear on what you are asking.

If so, you...

    Hello, I'd like to reproduce the kernel and root filesystem binaries from the PSP 2 release. Since this looks like an angstrom distro, I set up OpenEmbedded and bitbake, specified argstrom, the 35xevm, and the CodeSourcery toolchain with these lines in local.conf: DISTRO = "angstrom-2008...

    I don't believe the OMAP35x Linux PSP Release 02.00.00.01 obtained from https://www-a.ti.com/downloads/sds_support/targetcontent/psp/omap35x/index.html is an Angstrom distro, nor uses bitbake to build. There is an OE/Angstrom recipe for the BeagleBoard. The instructions to build the Linux PSP are...

    Thanks, Ramsey. Yes, the device is OMAP3530, not sure what silicon revision. (I'll work on this in parallel with our discussion.) I'm not sure I can match up the LPM_off() code (in modules/omap3530/lpm_omap.c) exactly with your 7-step sequence, so instead here are the major comments (/* ...

    CONTROL.CONTROL_IDCODE reads back a value of 0x2B7AE02F, so the silicon revision is ES2.1.
