RE: OMAP Intercore locking

Hi, You can look at DSPLink MPCS module. It provides a two-processor software spinlock. We also have a MPLIST module, which is a shared memory list protected with this MPCS lock. http://wiki.davincidsp.com/index.php/DSPLink_Overview Regards, Mugdha -Original Message- From: davinci-l

have you ever seen this error?

I'm trying to develop my application based on encodeCombo on a dm6446. When I try to open codec engine I get this error: Processor_create: execv failed: Permission denied Comm_locate:msgget: No such file or directory error: could not open engine encode : Unable to locate the server on the DSP By

RE: Start-up boot problems

Thanks guys! The EABI configuration was the problem. My busybox was not compiled with AEABI, so I disabled it in the compiler config, and now I get to the shell prompt. However, there seems to be a problem with the serial interrupt now. While pressing keys generates a serial interrupt, no tex

[PATCH 2/2] ARM: DaVinci: DM646x PCIHOST: PCI Host Driver

Hi Hemant : i tried to use your patch with 2.6.10 kernel, I have a PCI backplane with minimum 2 slots . The DM646x EVM (without h/w modification ) is put in one of the slots and a 10/100 Mbps Ethernet PCI Adapter was used in other slot. when my linux kenerl run to this function void dm646xevm

RE: [PATCH 2/2] ARM: DaVinci: DM646x PCIHOST: PCI Host Driver

Hi Lingyun, It is strange that you are hitting that code, because on unmodified EVMs, the code inside 'if' block in dm646xevm_pci_setup is not supposed to be executed. The reason is, when the (unmodified) EVM is put into PCI slot, the on-board logic automatically enables PCI (EMIF disabled). C

RE: have you ever seen this error?

Double check that your ARM-side .cfg script is correctly setting the OSAL .runtimeEnv to "DSPLINK_LINUX". Something like this: == /* Load support for the Codec Engine OSAL */ var osalGlobal = xdc.useModule('ti.sdo.ce.osal.Global'); /* Configure CE to use it'

Re: have you ever seen this error?

(again, it seems the first time it did not have the list as destination). It seems to be correct, I'll paste it so that you can check, do you have any other idea? var osalGlobal = xdc.useModule( 'ti.sdo.ce.osal.Global' ); osalGlobal.runtimeEnv = osalGlobal.DSPLINK_LINUX; var TraceUtil = xdc.useM

RE: have you ever seen this error?

Which version of CE are you using? I want to cross-check your trace output below against the actual sources. Your .cfg script below looks right, but the trace output [way] below indicates that the wrong .runtimeEnv is being pulled in. Namely, the trace indicates that the "LINUX" runtimeEnv ra

Dear Chris, I think I found the problem while I was writing a long response to your email with all the details. I found out that I linked to some wrong libraries. Let me explain a bit. I am compiling my program directly on the arm board, I have the rootfs mounted on nfs. The only thing I

2.6.30 EDMA/Audio Lockup

I modified 2.6.30-rc7 which was pulled from davinci git last week to support our dm6446 board. In order to get i2s configured properly I had to make some changes. There was no longer a definition for the CLKSM bit. hwparams does not read the SRGR register, but instead simply sets FSGM which
