Bare Metal interface access on MX7

demoniacmilk — Thu, 28 Dec 2017 15:54:33 GMT

Hello community,

to verify custom hardware I'd like to read/write some bytes to/from different interfaces/memory.

Beacuse I dont know anything about Linux (and the linux part for this project will be done by someone else) I would like to program these tests bare metal.

KEIL is available, what kind of emulators may I use? Any?

Are there any examples for bare metal interface access?

Is the M4 capable of accessing the DDR RAM or is this RAM access exclusive for the A7? Again, any example code?

Thanks and regards,
Lars
