| |
Hello
We were using this driver successfully with 2.4 kernels on trizeps Strong-ARM boards, then, when we ported our patch to 2.5, the situation changed - sending data TO the board from, say, a PC works, but not the other way round... I enabled debugging in the driver, so, I see that transmit_chars is called, the parameters are fine, then it calls serial_out - but nothing happens... UART is an ordinary 16550A. Any ideas as what has changed between 2.4.13 and 2.5.6 that would require special attention are welcome.
