Also, could you post a snippet of your lvds-panel and backlight device tree nodes?

Did you try a really long time span like 2000ms?
Just to make sure if its an timing issue or a driver sequence issue.

Thanks for your answer.

Meanwhile i found exactly the same and i tried i by setting post-pwm-on-delay-ms but i got still a white flashing while boot up. I would say it even get slightly longer...

Hello,

unblank_delay basically delayed the enable of the backlight by introducing a msleep at the end of the ipu init function.

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.

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 …
