Subject: [ECOS] CS8900a interrupt problem on EB40
Date: Mon, 06 Oct 2003 09:51:00 -0000 [thread overview]
Message-ID: <OFE963DC02.8274C808-ON48256DB7.003478C7-48256DB7.0035F064@MXIC.COM.TW> (raw)
CS8900a is connected with IRQ1,ethernet cable is not connected.
after cyg_drv_interrupt_unmask(),
EB40 generate interrupt all the time, the AIC_IPR is 0x00070005(IRQ1 is
pending)
the IRQ bit is set, is it mean interrupt?
but read cs8900a register CS8900A_ISQ, always 0, that should be no
interrupt.
I don't know why there is always interrupt?
thanks for any help!
