Hi, Have you used the Freescale QUICC Engine (QE) ATM mode with a Linux based product ?
I am currently using the "fua" driver obtained from Freescale MPC8360E_PB_K26_20081112-LTIB.iso CDROM image. The "fua" driver was written for kernel 2.6.22 (2007) and I have ported it forward to kernel 3.3 (2012). My board has an MPC8358 and SUNI PHY. I am testing the fua driver with the atm-tools and aburst, and using a loopback cable. The ported fua driver is able to open an ATM connection and send and receive messages. I can use awrite and aread to send and receive ascii characters. Problems: * If I open three or more ATM connections, all ATM transfers stop, and the ethernet driver (ucc_geth) also stops working. To recover I have to reboot. Urg. * UBR transfers seem to be treated as if they are a 100 Mbps CBR connection. I was expecting UBR to fill all of the unused bandwidth. * I'm finding and fixing a lot of minor bugs that crash the driver. My other reference is the mpc8360 SAR driver (http://mpc8360sar.sourceforge.net) which is even older (patches against kernel 2.6.11). If someone on this list is sitting on an updated fua driver or similar QE ATM driver, could you send me the code. Better yet, can I help you push it out to a github or similar repo ?
