Hello Marcello Bellini,

There is not a real time OS BSP for the Cortex A7 on the i.MX7. Most users use the Cortex M4 for real time operations and run Linux on the Cortex A7 so this is the supported configuration.

You may port a real time OS on the Cortex A7 yourself but it’s not a trivial task. There is also NXP Professional Services who may be of help.

My apologies for the inconvenience.

Hello gusarambula

the problem is cortex M4 does not support 64 bit floating point in HW and it is has low performance

for my application.

Hello Marcello Bellini,

I understand the predicament. You may certainly run a real time operating system on the Cortex A7, but there is not a BSP providing this solution so you would need to do the porting.

My apologies for the inconvenience.
