Subject: 8xx spi completion sometime doesn't generate an interrupt
Date: Fri, 2 Jun 2006 17:08:48 +0200 [thread overview]
Message-ID: <200606021708.48814.antonio.dibacco@aruba.it> (raw)
As far I understood the spi bus device of mpc8xx works independently from the
attached device (in my case a dataflash m25pe80). Thus I don't understand why
sometime when I start an SPI transfer I don't receive an interrupt for the
completion of this operation. I wait 50 ms for this interrupt and sometime it
doesn't happen. Anyone had a similar problem?
Bye,
Antonio.
