Other Parts Discussed in Thread: OMAPL138
Hello.
We use OMAPL138 Logic PD board. We have boot processor from SD (QUMO SDHC, class10). Our application (run under linux, lastest EZSDK) writes files to the same card from DDR by fwrite(). Speed about 1MBytes/sec. When we try to check SD speed under windows or under linux to write files, so speed is about 10MBytes/sec. We have tried to tune sysctl by vm.dirty_background_ratio and others, but this has not led us to the decision problem.
What's the problem? We've found some messages in forum about issue, but no one was answered.
Any help will be appreciated, thanks.
