Subject: spi_topcliff_pch: reload issue
Date: Tue, 22 Feb 2011 10:22:11 +0900 [thread overview]
Message-ID: <7FC6F7C4A6284C0FBD95D71D76B7528D@hacdom.okisemi.com> (raw)
Hi,
issue: after reload the spi module, it can't do SPI communication.
We have faced issue when execute the following command.
insmod xxx.ko(Then, /dev/spidev0.0 is created with success)
rmmod xxx.ko (Then, /dev/spidev0.0 is deleted with success)
insmod xxx.ko(Then, /dev/spidev0.0 is created, however, below error message is showed)
0000:02:0c.1: registered master spi0
0000:02:0c.1: chipselect 0 already in use
0000:02:0c.1: can't create new device for spidev
Do you have any information about the above ?
kernel=2.6.37 on FC14
With Best Regards,
