[ECOS] Regarding delays in UDP (ethernet) ISR
Wed Mar 12 05:19:00 GMT 2003
We are using eCos for PowerPC cpu.
We are observing that net ethernet (10Mbps)
bandwidth is some 800Kbps.
With default ecos.ecc's settings, our bandwidth was
We tried with more number of BDs for the SCC, more mbuf area, more
cluster area. We even configured more BDs than ecos.ecc's limit. We
increased network thread's priority. And then we arrived at 800Kbps
only. We observe that ethernet controller (in our
case it's PowerPC's SCC) delivers packet to eCos, but
eCos is not delivering all packets to application.
Some UDP packets are just lost. We don't have any ethernet collisions.
Can you tell what could be troubling?
We are using eCos 1.3, can newer version help us?
Thanks & regards
