Does there exist some hw conflicts if ipcf and llce driver working together on m7 core side ?

[fengxianeric]

Is it feasible if we want to make it together work on m7 hw ?

[fengxianeric]

thanks

integrated sw will be growing up size and I worry about sram volume not enough.

thanks

Hi,

Memory is not infinite, that is true on almost all embedded systems. Good SW management is required to develop the embedded application.

Please, let us know.

Hi,

We don't see any indication that suggests that both LLCE and IPCF cannot work together within the HW provided under the M7 core. For which, we can say it is feasible.

Please, let us know.

TO double-check, are you sure about safe memory layout compliant with each other, today I tested integrated sample, no work yet.
THanks

Hi,

As said before, there does not seem to be a HW limitation that could impact the implementation for both IPCF and LLCE.

If there is a problem, could be related to the SW integration.

Please, let us know.

To correct my addresses plz ?

Hi,

This linker is being used on which example? If both, which one is failing?

Please, let us know.

[fengxianeric]

Thanks caring.
It is being used from single instance of ipcf sample package. The image file can be bigger (>5M) after integrating with lice sample, which made uboot hang-up. If I moved forward int_sram_no_cacheable address, it would block a53 linux kernel booting.
Thanks

Hi,

Since IPCF linker is more complex than the one present under the LLCE examples, instead of copying the LLCE linker to the IPCF example, why don't you copy the IPCF linker to the LLCE example?

We are seeing that the LLCE example can run using the IPCF linker, which should help with the application you are trying to implement.

Please, let us know.

[fengxianeric]

Hi, to clarify I am using ipcf sample linker and config file just because we make it bigger after adding llce code.

Thanks caring

[Daniel-Aguirre]

Hi,

We still might not be understanding. Are you using the IPCF linker file under the IPCF project? Or are you using the LLCE linker as mentioned before?

Please, let us know.

I am growing ipcf code and use same building tool chain tresos and make build.

Thanks again
