An unusual problem about CF card

Hi, all

I ran into a big problem. We are using a program to read data from a serial
port on XPE image which strored in CF card. The hardware and program are the
same, and the images are the same too. But some of the devices doesn't
work.(The detail is when we launch the program for the first time after
system boots up, it failed to read data from the serial port. After we close
the program and launch it again, then it can read data. This is a big
problem since we want to launch the program automatically when system boots
up.)

When we switch the CF card from the good device to the bad one, it works! We
make the image to each CF card in the same way. So we doubt if there is any
problem with CF card. We use SanDisk Ultra II 512MB . Does anybody met such
a problem with CF card? Would there be any potential problem with CF card
comparing to mechanic hard disk?

Hi, Maverick!

It could be timing problem. PnP for instance doesn't have enough time to
recognize com ports or something like this. Can you try to launch your
app with a small delay?

But after we remove the program from the startup directory, and launch it
two minutes after the system boots up, we get the same error. And close the
program and open it again, it works. So strange.
