[Bug]ran out of RAM during transforming files
Recently,I try to transform some large files into my Prime V2 ,but something went wrong . I don't know why after I finished transforming and a long loading , it just told me "Out of Memory",?
It really made me crazy these days , is it because the OS && connectivity kit?

What kind of files were they and how large were they?

It probably simply did exactly what it said, and did not have enough memory to process the file, assuming it was a .hppl program file. Can you break the source file into several smaller files and try to download them one at a time?

They are about 2,000 jpg files,I used script to process a video into pictures so that I can view it on calculator.
So,I have to divide them into several parts.
The connectivity Kit is just a toy,which is the worst as far as I know!

You probably used the wrong shelf row in the electronics market.
A smartphone would have been more useful for your needs.

Err... You're trying to view a video on a calculator and because the ConnKit is struggling it's just a toy?

I was having a similar problem with my microwave. It completely fried the DVD in it that I was trying to watch.

Sorry, I thought there could be a real issue here.

I'll just move along...

Or in this case. "if you have 2000 nails, every tool looks like a hammer". Smile

RE: [Bug]ran out of RAM during transforming files
The reason it runs out of memory is because to successfully send file from the connkit it uses about 3x the size of the total content. 1) for the incoming data 2) to decompress the zip compressed data sent 3) the write the data to permanent location. 2000 images is going to be a lot of data.... Out of curiosity, how much is it?


We never really intended people loading pron vids as image stacks onto the calculator.... Sorry.

Well,I see...I just want to ....make a demo ....to show this calculator's ability...
But I'd never met this case before, even on my PDA.
The size of these files may up to 30MB,so I have to divide it into part。
PS: I found that at some moment which has a small amount time redundancy , the video plays slower (like VNC's compression algorithm).Why?
PPSS:why HP doesn't release SDK for prime so that we could dance without leg irons?
