Hello, we are busy adding multicast support to the AT91 EMAC Ethernet driver.
As code size is often important for eCos users, I was thinking to add an #ifdef around the multicast code. The setting is in /io/eth/current/cdl/eth_drivers.cdl: CYGINT_IO_ETH_MULTICAST. But that is always used this way: 'implements CYGINT_IO_ETH_MULTICAST' in the driver cdl (e.g. /devs/eth/cl/cs8900a/current/cdl/cl_cs8900a_eth_drivers.cdl).
The problem is that you cannot add/remove that option yourself: from ecos.ecc: '# This value cannot be modified here.'
So once somebody as extended a driver to support multicast, that code is present in your binary (control() function), even if you don't need it.
That's OK for me. But I don't it's ok for everybody?? Then we could change the cdl option. Kind regards, Jürgen -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
