Hi,

-- Yes, need help for the same.
I didnt get the below modifications described in the previous reply. Do i need to modify kernel like this? Sandeep Sivadas

JC 08:50 PM Software Development: RE: Hello World on DSP

Hi Arun,
How are you loading the processor with the ARM RTOS and DSP RTOS? What boot media are you using, you said you aren't using sdcard? In my experience, we would boot into u-boot and then use u-boot to load the FPGA, DSP and AR... Jonathan Cormier

> The pinmux should be set up by u-boot, there should be no need to touch the pinmux in the DSP. There is a wiki page, on how to configure the pinmux in u-boot. https://support.criticallink.com/redmine/projects/mitysom_am57x/wiki/U-Boot_... Arun Krishnan

It looks like the mmc2 config is different on your yocto build. It's missing the pinmux pinctrl entry, the max-frequency is different, etc. Do you need help getting your changes from the native Linux build into the yocto build?
We w... Jonathan Cormier

SS 12:29 PM Software Development: RE: eMMC not enabling on Docker based image buiding

dtb files in the boot folder of native build and docker build a... Sandeep Sivadas

Note your "non working" boot log seems to be truncating several lines, not sure how you captured it but that's pretty odd. Jonathan Cormier

Hi,
_Which kernel are you using?_ - 4.19.94-yocto-standard
_Can you please share whole boot logs for working and non-working cases._ - I am attaching the log files here
_
Also the pinmux you sent me doesn't make sense_ - Sorry, i... Sandeep Sivadas

JC 03:59 PM Software Development: RE: eMMC not enabling on Docker based image buiding

Which kernel are you using? Can you please share whole boot logs for working and non-working cases.
Note: It doesn't make much sense that a docker build vs a native build would behave that differently. The emmc is all setup in the ... Jonathan Cormier

SS 10:26 AM Software Development: eMMC not enabling on Docker based image buiding

Hi,
I tried to build am572x image using docker build environment with eMMC enabled. But my image not detecting eMMC.
I have modified the kernel file am57xx-mitysom-baseboard.dtsi as
&mmc2 {
status = "okay";
