I have built upgradeable firmwares before for linux systems, but never for a MCU.</P><P>I have been reading about the Kinetis Bootloader <A href="http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/kinetis-cortex-m-mcus/kinetis-symbols-footprints-and-models/kinetis-bootloader:KBOOT?tid=vanKBOOT" title="http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/kinetis-cortex-m-mcus/kinetis-symbols-footprints-and-models/kinetis-bootloader:KBOOT?tid=vanKBOOT">Kinetis Bootloader|NXP</A>​ ​. Do you think it would be a good approach to supply the device with the bootloader and then in the future release a PC software to flash the new firmware via USB?</P><P></P><P>Thank you and best regards!</P></BODY></HTML> Wed, 10 Feb 2016 08:47:36 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/Upgradeable-embedded-software-built-on-Kinetis-MCUs/m-p/499833#M31204 juanruiz 2016-02-10T08:47:36Z Re: Upgradeable embedded software built on Kinetis MCUs https://community.nxp.com/t5/Kinetis-Microcontrollers/Upgradeable-embedded-software-built-on-Kinetis-MCUs/m-p/499834#M31205 <HTML><HEAD></HEAD><BODY><P>Hello Juan Ruiz:</P><P></P><P>For embedded devices bootloaders are extensively used and the most typical approach for firmware updates of products in the field.</P><P></P><P>In the link you posted there is a table with the Kinetis devices currently supported by <STRONG>KBOOT</STRONG>.</P><P></P><P>- Some parts have a dedicated ROM memory with the bootloader firmware pre-loaded, so you can use the entire flash memory space for your application.</P><P>- The devices under <STRONG>Flashloader</STRONG> column are preprogrammed in factory with a one-time use loader.
