I downloaded the USB Host Lite (Beta) example software from NXP.COM from here:
The first thing I noticed is within the Host_Init() function, the base memory address for the data structures is as follows:
// For chip revision V01 and later
HostBaseAddr = 0x20080000;
According to the user's manual, this section of memory is reserved for the AHB peripherals...
[ref: UM10470 LPC178x/7x User manual Rev. 1.4 — 10 June 2011, page 14, table 3]
Am I misinterpreting this table?
I was thinking about relocating this base address to 0x2000000, which is described as "Peripheral RAM - bank 0(first 8kB)".
Anybody else run across this problem?
