I am using eCos downloaded from CVS 8 months ago. while sending packet
using driver functions (if_i82559.c) same packet is going out twice. i
have made sure that my code is not sending twice. i am getting following
assertion fail from driver
CYG_ASSERT( rxstatus_hi & RFD_STATUS_HI_EL, "No prev EL" )
have anybody faced this kind of problem?? when can this happen ??
plz help me out.
TIA

I had the same problem. In my case follwing 2 in if_82559.c where responsible.
Mask82559Interrupt()
UnMask82259Interrupt()
I didn't have defined
CYGPRI_DEVS_ETH_INTEL_I82559_MASK_INTERRUPTS
Mask82559 will then use cyg_drv_interrupt_mask().
but for my target (sh4), cyg_drv_interrupt_mask was a NOP for the
IRQ pins i had used.
furthermore UnMask82559() should restore the irq state, but
cyg_drv_interrupt_mask() will fail if nested calls occur.
