GNU GCC and Kinetis USB MSD Bootloader

[tipofthesowrd]

Hello,

has anybody succesfully compiled a working USB Mass Storage Device bootloader using GNU GCC for ARM Embedded toolchain.

I have several projects running with the ARM Embedded toolchain and would like to present customers with a bootloader which can present itself as a USB Disk.

I'm currently using the KL25z and files based mostly on AN4379.

However, when assembling Loader.c there are errors such as 'bad instruction: halt'.

Any help?

Hi

If you need professional quality boot loaders for any Kinetis (KE, KV, KL, K) parts you can get them from here:

µTasker Kinetis support

Builds out of the box with (including GCC):

• Freescale's Kinetis Design Studio (KDS)
• Freescale's CodeWarrior 10.x
• Rowley Associate's Crossworks
• CooCox CoIDE
• IAR Embedded Workbench
• Keil µVision
• Green Hills
• Atollic TrueSTUDIO for ARM
• Standalone GCC from Makefile
• VisualStudio for Kinetis simulation

With USB-MSD (PC, Windows 8.1, MAC compatible), KBOOT serial/USB-HID, SREC, SD card, Ethernet (for parts with ENET or with SPI based controller) in parallel (configurable for one or any mixture).

Specifically for KL25:

µTasker Kinetis FRDM-KL25Z support

µTasker Kinetis TWR-KL25Z48M support

Fully documented and supported: http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.PDF
