Hi All, I am working on DM355 and am facing some issues because of scheduling behavior of threads. Basically since the scheduling mechanism of LINUX is based on time slices a lower priority thread is able to preempt a higher priority thread. Is it possible to make the scheduling policy of LINUX real time to prevent preemption of a thread with higher priority?
Thanks in advance.

When I compile the readwrite sample on the side of DSP (DSPLINK/dsp/src/sample/readwrite), there is an error : /bin/sh: /opt/ti-tools/c6000/cgtools/bin/c16x: no such file or directory Where can I find the file c16x ?

The production DVSDK release is 1.30.00.40 which includes the production LSP component – 1.20.00.014. There is a latest LSP update 1.20.01.004 (patch level 14 release) that includes the patches for custom MMC/SD stack that supports SDIO and SDHC, along with performance improvements. These are the same patches Jon has mentioned, but are modified (very minor modifications) to get applied against the production release. https://www-a.ti.com/downloads/sds_support/targetcontent/psp/mv_lsp_1_20/index.html Note that the MMC/SD driver in the baseline code does not support SDHC cards.

The LSP is 1_30_00_23, but we are also running SDIO driver patches from TI. We had a 4GB SDHC card working on the EVM but are now using our own board, got the 8GB card later so only used with our new board. I doubt it's a pcb issue though. -- Jon Povey, Design Engineer [EMAIL PROTECTED] | +44(0)1280 825983 ________________________________ From: António Silva [mailto:[EMAIL PROTECTED] Sent: 12 September 2008 14:58 To: Jon Povey Cc: [email protected] Subject: Re: MMC/SD card capacity limits Hi Jon, First of all, thanks for your reply. I want to ask you a few questions: 1. The SDHC 8G memory card is class6? From which brand? (My memory is Kingston class6) 2. The LSP that came with the EVM is version 1_30_00_23 or 01_20_00_014<https://www-a.ti.com/extranet/cm/product/dvevmsw/dspswext/download/mvl_4_0_1_demo_lsp_setuplinux_01_20_00_014.bin> (this last updates in June 2008)?

I have a dm355 board and i just tested and it can recognize SD cards at 2G and 4G, but I am inserting and 8G SDHC card, and the behaviour is very strange. When the card is pluged linux doesn't run and the card reboot automatically. Does anybody have had this problems?
