TDA4VM: Linux remoteproc

Hi Cherry Zhou,

1) Does the following program run automatically on power up? How to run manually with constant power? 

Yes, this gets loaded on mcu1_0 automatically. In order to change it, you need to rebuild uboot and use it.

2) Regarding Linux remoteproc, how to apply and operate it?

Did not get it. Linux does use remoteproc driver to load the core firmwares.

Hi Brijesh,

Thanks for your support.

Do we have any docs could specify how to use it?

Thanks and regards,

Hi Cherry Zhou,

Can you please documentation in PSDKLA? 

Typically this driver looks for the firmware with the specific name in the /lib/firmware folder and if it is available, it tries to load the firmware on particular core.

Hi Brijesh,

How to receive/transmit CAN data in EVM? The program has been copy to SD card.

Thanks and regards,

Hi Cherry Zhou,

I did not get it, which program is copied to SD card? Have you added this code to vision apps?

No, can they run it if add it directly to /opt/vision_apps? (my apologize since the customer is fresh and we may need to take more time to figure out the case here).

Thanks and regards,

Cherry

Hi Cherry Zhou,

No, the firmwares are stored in /lib/firmware folder with the specific name. I would suggest to run "make linux_fs_install_sd" command from vision apps folder to copy all firmwares correctly.

This had been done. 

How do the output information print out on the board? And how is the function App_ConsolePrintf implemented?

Thanks and regards,

Cherry

Hi Cherry,

Are you trying to run some MCAL example on mcu1_0? Is vision apps also running on other cores? Then please make sure to use memory reserved for this core in the MCAL example.  

In vision apps, we typically use appLogPrintf API to print the log messages, this messages then comes on the Linux console. If possible, can you also please replace App_consolePrintf with appLogPrintf API?

Hi Brijesh,

How to add csl_mcan_evm_loopback_app_mcu1_0_release_strip.xer5f to DM？

pdk_jacinto_08_04_00_21\packages\ti\binary\csl_mcan_evm_loopback_app\bin\j721e_evm/csl_mcan_evm_loopback_app_mcu1_0_release_strip.xer5f

Thanks and regards,

Cherry

Hi Cherry Zhou,

Before that, can you please check if SciServer is integrated in this example? Because without SciServer integration, none of the examples would work. Once SciServer is integrated, we can easily integrated it to the DM, assuming memory map changes are taken care.
