Sneha,
I've been noticing that when writing to USB (and possibly any medium), the entire system occasionally stalls. I believe this might be during the flush operation, as the stall is very periodic (about every 5 seconds). Do you know how I can avoid this stall? I did not expect the filesystem write operation to cause all the threads in application to not run for several hundreds of milliseconds. -- Pete ----------------------- Steve, Were you trying to patch the Beta kernel with patches from "patch level 14 release"? You may have missed the LSP 1.20 GA release. The patches from "Patch level 14 release" cleanly apply to the LSP 1.20 GA kernel. The default series file picks patches 1, 9 - 14. The patches 2 - 8 are for the custom MMC/SD stack. LSP 1.20, with patch level 14, we have reported the following - USB MSC Host Read: 6.4 MBytes/sec USB MSC Host Write: 6.3 MBytes/sec The procedure followed to measure the performance is documented in the datasheet - http://focus.ti.com/lit/an/sprs496a/sprs496a.pdf BTW, we also have a LSP 2.00 Beta release, which is based on MV Pro 5.0.0 (2.6.18) on the software update advisor site. USB MSC Host performance has improved with this release: USB MSC Host Read: 13.4 MBytes/sec USB MSC Host Write: 7.3 MBytes/sec Thanks Sneha
