Olivier,
It is a known issue and we've been working to get a solution for SD / MMC performance improvement. We'll be posting a patch for mvl 2.6.10 (dvsdk / dvevm v1.20) by the end of this month. Regards, Thom ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Olivier Singla Sent: Saturday, September 01, 2007 7:54 AM To: [email protected] Subject: SD card access very slow (77 KB/sec) Hi, I recently played with the SD card system, using dvevm 1.20. I noticed that writing to the SD is extremely slow (< 80 KB/sec!), while using the same SD on a USB card reader on my PC gives 3.7 MB/sec. Is-it a know issue with the current linux DaVinci SD device driver, poorly written or designed ? Is there any plan to improve it if this is the case ? The TI documentation for the DaVinci SD interface (sprue30b) does not provide performance numbers. Thanks, Olivier Singla Integrian, Raleigh, NC, USA
