As far as I know, it seems the CSR library release come with Windows CE BSP
dose not handle the simultaneously Ethernet access well.
This issue could be happened when using both NPE for Ethernet access.
The issue has been workaround by adding a SpinLock around
ixEthAccPortTxFrameSubmit function in
SRC\DRIVERS\NET\IXP4xxEthNpe\IXP4xxEthNpe_send.c.
But take a look at the SRC\DRIVERS\NET\IXP4xxEthNpe\sources @ about line 68
which define the TX_SPINLOCK C macro if and only if IMGNOTALLKMODE is *not*
defined (ALL Kernel Mode); before CE 6, it is possible to enabling this
feature but in CE 6, there is no more all Kernel Mode (in fact, the NDIS
miniport driver is loaded into kernel space in CE6) so that SPINLOCK is
never being define in this case.
So you may fix it by moving the "CDEFINES=$(CDEFINES) -DNO_TX_TRANSLATION"
line out of the !IF !ENDIF scope or you may remove the code from line 57 to
61 and having the SOURCES code like this
CDEFINES=$(CDEFINES) -DNO_TX_TRANSLATION
# currently shall enable the CHECK_BUFFER_COUNT
# or the NPE will hang while too many buffer in one packet ( > 3)
CDEFINES=$(CDEFINES) -DCHECK_BUFFER_COUNT
CDEFINES=$(CDEFINES) -DTX_SPINLOCK
# CDEFINES=$(CDEFINES) -DFORCE_TX_COPY
!if "$(BSP_NDIS_STATIC_TX_POOL)" == "1"
CDEFINES=$(CDEFINES) -DNEED_DRAIN_BUFFER
!endif
Either way should enable the TX_SPIN LOCK and solve you issue and the later
way might have some advantage on network performance. (It was optimized for
IP Routing scenario)
