Unreliable response from GLK19264-7T-1U (USB)

kevan.t · Post by **kevan.t** » Fri Jul 25, 2008 3:50 am

After a few hours of normal operation, my GLK19264-7T-1U (USB) stops responding correctly to the "Get Filesystem Directory" command. Instead of returning the entry list, it just responds with a single byte with the value "0xFE".

No matter what I do I cannot correct this. After a few hours, seemingly randomly, the device may start working again.

What does this response mean?

This lack of reliability is really threatening my ability to meet my project deadlines.

Please help !!!

Is it just this particular command thats causing problems? can you write text to the unit or draw a bitmap from memory when the unit is in this state?

Hi Kevan,

I believe this issue is related to your upload difficulties, so I've answered the previous post over here. It looks like you are having a problem with memory in general, so once we get the write working properly, this read issue should be resolved as well.
