I have been asked to create a bootloader for the device so it's firmware could be updated in the field via USB drive. I found a USB bootloader sample discussed in one of Freescale’ s document (USB_BootLoader_AN4368.pdf). This sample uses MCF52259 processor which I presume should be similar to ours, and that gives me confidence that bootloader can be developed for MCF52277.</P><P>&nbsp;</P><P>Can someone guide me and point me in the right direction with regards to software code and/or people references?</P><P>&nbsp;</P><P>Thank you.</P><P>&nbsp;</P><P>- Mahesh</P></BODY></HTML> Fri, 09 Dec 2011 06:13:13 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Bootloader-for-MCF52277/m-p/189101#M8120 med_device 2011-12-09T06:13:13Z Re: Bootloader for MCF52277 https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Bootloader-for-MCF52277/m-p/189102#M8121 <HTML><HEAD></HEAD><BODY><P>Hi</P><P>&nbsp;</P><P>See <A href="http://www.youtube.com/watch?v=H4TYM9jY2-g" rel="nofollow" target="_blank">http://www.youtube.com/watch?v=H4TYM9jY2-g</A></P><P>This is shown on the Kinetis but also work on the M522xx range of parts. <EM>It hasn't been used on the MCF52277 though</EM>.</P><P>&nbsp;</P><P>Regards</P><P>&nbsp;</P><P>Mark</P><P>&nbsp;</P></BODY></HTML> Fri, 09 Dec 2011 06:40:23 GMT https://community.nxp.com/t5/ColdFire-68K-Microcontrollers/Bootloader-for-MCF52277/m-p/189102#M8121 mjbcswitzerland 2011-12-09T06:40:23Z
