Hi Greg and all, As part of porting USB Host driver for RX65N, I am referring to LPC17_40 USB Host port. Here are some of the points, where I need your suggestions. Please let me know if you have any pointers/ other references on this. HCCA (Host communication area details), TDTAIL (Transfer descriptor details) and EDCTRL (Endpoint descriptor details) are referred as respective structures. LPC17_40 has these structures located at some RAM Area (I think, LPC17xx has dedicated memory for USB Host or something like that) and uses this memory area for these structures (where start address is fixed at starting point of memory, and with each size, the next structure is referred). In RX65N, would it be OK, to use normal memory and allocate these structures statically - in the beginning of the file itself? Or do you suggest to allocate memory in the init function *__usbhost_initialize () function and use them? With best regards, Phani.
