Hello,
can anybody explain me why I can find in the docs of LPC2387 and LPC2361: "USB 2.0 device/host/OTG with on-chip PHY ...."
and in the "UM10211 from nxp" (user manual for 23xx) in chapter 13, usb host controller: "The USB host controller is available on the LPC2388 _only_"
I want to boot from a usb stick for update the firmware of my application. Is there any solution to boot from usb stick with LPC2387 and LPC2361? If not: is it possible with sd-card?
Thank you very much for any links, code, hints whatever.
Greetings from germany, Treess
is there anybody knowing this LPC2387 or knows for sure if it is with or without usb host?!?
This note in the MCB2300 User's Guide might help:
Revision B LPC2387 devices with a date code of xxx0836xx or higher support USB-OTG. MCB2387 boards built with the these LPC2387 devices are populated with the USB "B" and mini-USB connectors. MCB2387 boards built with older LPC2387 devices will not have the USB "B" and mini-USB connectors installed.

To add to prior comments, the LPC2387 silicon errata sheet version 1.1 from November 2008 (www.nxp.com/.../ES_LPC2387_2.pdf) states the following:
Note 2: Devices with a date code prior to 0836 (manufactured before week 36 in 2008) have USB 2.0 full-speed dual port device with on-chip PHY and associated DMA controller. Parts marked with date code 0836 or later have USB 2.0 full-speed dual port device/host/OTG controller with on-chip PHY and associated DMA controller. Please refer to page 2 of this document for details on how to identify the date code.
The date code is interpreted as follows: The typical LPC2387 devices have the following top-side marking: LPC2387xxx xxxxxxx xxYYWW R[x]
