I just posted Improve SD card Read and Write speed on Task Tracker. Feel free to discuss and make suggestions here.
Improve SD card Read and Write speed was updated.
Status went from Proposed to Open.
Priority went from Unassigned to Minor.
What speeds are you seeing that are too low on which boards?
there was the thread on speed improvement that someone had made by going to RLP - I think it’s noted in this thread https://www.ghielectronics.com/community/forum/topic?id=16057
I haven’t tried DAT 's suggestion yet, but it’s pretty easy to check the clock speed with an oscilloscope to confirm that it works correctly. Using my registry hack does seem to make a big difference, but I don’t know how close netmf is getting to the bare metal performance.
The SD clock can make different on some cards, but actually not too much.
We are planning to do something else inside FAT system.
Improve SD card Read and Write speed was updated.
Status went from Open to Closed.
@ John - Does this mean… Speed is improved?
@ RobvanSchelven - Our tests show acceptable speeds. If there is a specific card or code sample that performs poorly, we can investigate that separately.
