Tested operating systems: Windows XP Pro with Service Pack 2 and Service Pack 3 Tested development boards: TWR-MCF5225X-KIT low-cost tower kit for MCF5225x family DEMOJM low-cost development board for Flexis JM family TWR-K60N512-KIT low-cost tower kit for Kinetis K60 family USB stack used: Freescales USB Stack with PHDC support v3.0 MCF52259 32-bit ColdFire V2 with USB, Ethernet, CAN, and external bus MCF51JM128 32-bit ColdFire V1 with USB (part of the Flexis JM family) MK60N512 ARM Cortex-M4 architecture with USB 2.0 full-speed OTG controller and 10/100 Mbps Ethernet This bootloader will work on all of these devices with few changes, and examples were written and tested on the followingFreescale microcontrollers: 0, October 2011įreescale USB Mass StorageDevice Bootloaderby: Derek Snellġ Introduction.1Ģ Functional description.2ģ Using the bootloader.9Ĥ Porting USB MSD device bootloader toother platforms.13ĥ Developing new applications.15Ħ Conclusion.20ĬoldFire MCF522xx parts that have USB Kinetis This bootloader was specifically written for several families ofFreescale microcontrollers that share similar USB peripherals.These families include, but are not limited to, the following:įreescale Semiconductor Document Number: AN4379Application Note Rev.
Systems since it requires no host software or driver It can be used with many different host operating Any user can use it with a little training. It does not require an application to run on the host. It does not require a driver to be installed on the host. The MSD bootloader described inthis application note is offered as another option, and has theseadvantages: For example,application note AN3561, "USB Bootloader for theMC9S08JM60," describes a USB bootloader that was writtenfor the Flexis JM family. The new firmware is copied onto this drive,and the device reprograms itself.įreescale does offer other bootloaders.
A device with this bootloader isconnected to a host computer, and the bootloader enumeratesas a new drive. Thisapplication note describes a mass storage device (MSD) USBbootloader that has been written to work with severalFreescale USB families. A product with aUSB port allows very easy field updates of the firmware.
