- Subject: [ECOS] problems with rltk8139 driver
Hi all,
I've a custom board based on XScale IXP425. I'm in the process of porting
rltk8139 driver on this board. Sending data are ok ( I use ethereal to
check), but receive fail. In receive buffer (rltk8139_eth0_rx_ring) miss a
few data -about first 20 bytes. In this data should be a receive packet
header, because it is zero driver doesn't receive more. Rltk8139_eth0_rx_ring
is allocated in cached memory but all reading are done by uncached memory
(MMU translate address). I check up on either memory region - it's the same.
I think this is not a problem of memory coherency ( I use
HAL_DCACHE_INVALIDATE macro and result is the same). It seems to me that chip
doesn't copy all datas.
