hi, there a way to use micro2440 without the dev board?
micro2440 with no board
Why should this not possible? Its a stamp/core module, that is made for custom base boards. The SDK or dev board is only for evaluation.
ok, but i can't find manual like how use it, all link give me not found error... There are guide how upload the OS and basic program, and setup USB host devices?
IIRC: a micro2440 installed on a standard dev board is functionally the same as a mini2440. any of the documentation for a mini2440 applies.
my purpoise is to use it without dev board, because it has to be put on a RC flyng model.. are there the schematics of the dev board? or at least of the micro, just to know what are input and what are output!
> are there the schematics of the dev board? Yes, here http://www.friendlyarm.net/downloads#schematics
i've to remember to look in the obvius place... you'll hear me if i'll have some other truble. Thank you
ok, i'm getting it... the circuit is enought simple, but there something i can't get.. On the dev board: U3, the USB HUB, doesn't have the code, what shoud i use? USBD use as VBUS USB_5V, i can't find USB_5V on drawing, maybe is VDD5V(used from all the other usb host as VBUS)? the 5V (for the board) can be get from a 7805 Voltage regulator from a LIPO battery (lipo battery has a voltage drop, at max it will be from 7.4V to 6.5V)? As i can understand i only need USBD to install linux and comminicate with the board,right? because i need only implement 2 or 3 USB host and obviusly the USBD Tomorrow i'll start to draw the circuit, i'll post the drawings, maybe someone is interessed, maybe someone else will correct some errors :-) now it's late, goodnight p.s. sorry for my english, if you cannot understand something please, just ask :-)

Better is a switching regulator. > As i can understand i only need USBD to install linux and comminicate > with the board,right? USB, COM port and JTAG (for first programming).
ok, but i cant find JTAG on schematics... also USBD have a link with TP2 CON1 but i can't understand what it is. remain a question, USB_5V and VDD5V are the same? USB_5V is used only from USBD but i cann't find where it came from..
Sorry, I forgot JTAG is already on the micro2440 stamp module. TP stands for Test Point and USB_5V is not connected because this is a USB device/slave port.
