It's a 25000kHz sd card.

config set sdcard maxfreq.khz 15000

did the trick. Setting it to 20000 was still giving grief.

Since forever I've been getting uart errors (4) - which seems to be an ERROR

It seems it gets easily overwhelmed.

For example while doing (From the web i/f) 'vfs ls /sd'  is fine (there are only 15 entries there) .. the command:
vfs ls /sd/log

causes a whole bunch of the above uart errors (l50 or so) interrupted by the output of the command results (50 or so files).  I'm not sure  whether it lists all of them.. but probably?

I was implementing file completion in 'vfs' command.. and it works except for when trying to complete in that directory.  I suspect that it's overwhelming the limited spaces in the complete buffer.. but also the messages queue is getting swamped by all the uart_event errors.

Thoughts?
