Hi,
I'm working on an embedded Linux project. We have already ported Linux kernel to our board,
implemented the serial driver, but when the shell(through minicom) start up for a few seconds,
it come up with the following problem:
I can't input any character including "Enter", means that the shell don't action at all.
After a while(about 40~80s), it come back to normal state, and all the characters I had input
display on the shell(through minicom)! After this, my linux work pretty well till I power off the board.
We can see that the serial port have received those characters I had input, means that the receive part
of the serial driver work well, but it the serial suspend for a while, and then come back to normal, So ,
I don't know where to change inorder to solve this problem.
Can anybody give me a hint? Thanks inadvance!!
