Load Apps from SD CARD, Execute in RAM

weblar — Mon, 20 Jul 2015 13:01:27 GMT

Hi,

I'm looking for someone to either shoot me down or to indicate whether this is plausible.

Could it be possible to write apps to run on a Cortex-M4 micro? Storing the ELF files on an SD card, reading them into RAM as and when necessary then executing at the entry point. Could these ELF files link to a common library which the main application on the Cortex-M4 uses (almost like a common API for the platform) as well as any ELF files on the SD card?

It all seems pretty feasible but I'm probably missing something huge.

Kev

Hello weblar:

Since you posted in this space I guess you are referring to a Kinetis MCU with Cortex-M4 core.

I guess your idea is achievable but I am not aware of such implementation. The closest project I know about is uCLinux in K70 platform by third party emcraft. The details are in their page:

Linux BSP for Freescale TWR-K70F120M

Sorry if my response is not concise, that is not a typical use case of Kinetis MCUs.

Regards!
