Hi, I've been doing some testing with SD card writes on the DM355 devkit. The performance is dismal.
I am using a kernel retrieved from TI's site on Apr 20/08. I built the kernel with the only change to the config being the inclusion of the resizer driver. On Windows Vista, my 150x 2GB SD card gets a write speed of > 4 GB/s over a 128 MB file. On the embedded system my write speed is 135 kB/s - an unbelievable 3%!! Has anyone looked at the SD driver and/or SD interface? I was not planning on touching this driver, never mind having to rewrite big chunks of it :( Peter _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
