You should get a similar functionality by adding the value …

Hello,

I want to port the unblank_delay=200 setting of "i.MX6 Linux Release B2020.04 (Buildroot)". Meanwhile i switched to using the panel-lvds devicenode. How can this be done?


Thank you in advance.


Greetings,

PS: What did this setting exactly…

Hello Mark,

in our download area "My F&S" under "Tools-Windows" you will find the "FSSBCProfiler_V104.zip". This tool shows CPU usage and RAM usage.
Hope this helps.


BTW: source samples see here: CPU Usage and OS function GlobalMemoryStatus (RAM).

Are there any apps that will show CPU Usage % and RAM % usage?

Yes, the Cortex-M can access the SDHC peripherals. However, there are
several considerations:

- XRDC must be configured in the ATF (BL31) to allow the Cortex-M to
access the corresponding SDHC interface.

- The Cortex-M must ensure that the required…

Thank you for the quick reply, fs-support_CS .

As you mentioned, I am using PicoCoreMX8ULP rev1.10.
Could you please explain in more detail about using SD_A? From what I understand, it uses the PTF and PTD pins. Is it possible to access them directly…

Hello Saturnion ,

For the Cortex-M, I would primarily recommend using non-volatile memory via the SPI interface.
At the moment, we are working on a new redesign of the PCore8ULP, which will indeed allow a PSRAM or NAND memory to be connected to the …

Hello,

Am I correct in understanding that the picocore8ulp does not provide any non-volatile memory accessible to the M33 core without involving the A35 core?

Regarding the SD Card B interface: SD_B_DATA0 and SD_B_DATA1 are routed through GPIOF, which I…

Hello,

You get an overview of all configured clocks and their actual rates. Maybe You can spot a clock that matches your measurement.

Do you use a LVDS Display? LVDS_Clock/7=Pixelclock, so 250Mhz/7 = 35MHz which would be…

Hello,
after upgrading to linux kernel 5.15 and running the GPU with etnaviv driver (before it was disabled), i see in EMC (german "EMV-Messung") a sharp spike at almost exactly 250Mhz, which i cannot see in the software version before (linux 4.9 with no…
