Download one of PCI DOS example for ISP1161 from NXP
"USB downloads: Host and OTG controllers: ISP116x" from NXP http://www.nxp.com/products/...index.html For example, from "Kenobi 1.3e" example, tr_gene.c handles control transfer, dev_ep.c executes enumeration. how the packets r send on usb lines? ... i have written code to send a device descriptor req to peripheral and it has return a stall but i am not sure that is it going on right track or not. Don't you use any hardware bus analyzer? It is difficult to develop host stack even for simple OTG device without bus analyzer. i am a bit confused abt the packets, handshakes, and frames Isn't it better to return to the basic, before attacking to the host controller?
