The above link gives steps on how to download and install Linux SDK.

Do you plan to bring them up using Linux?

Hi Keerthy,

Thank you for the reply.

I want to build Yocto Embedded Linux, load into TDA4 board, connect 4 Cameras (2-Mipi, 2 USB-C).

1) Do I need to select target as arago-core-psdkla-bundle

2) Is there a way to flash image using USB or Ethernet?

3) Could you please share link to start compile (gcc), load, run application programs for other interfaces like GPIO, I2C, SPI, UART etc..

Thank you

Hi Neeraj,

I really doubt USB based camera is supported. I can check and get back.

For MIPI camera, which SDK are you planning to use? Are you planning to control it from Linux or RTOS?

We have support for MIPI camera on both RTOS and Linux, but only not simultaneously.

Are you using PSDKLA or PSDKRA SDK?

Where do you want to flash the images? Is it on SD card? then you could do it on your host machine..

Please refer to the userguide of PSDKLA or PSDKRA to install required tools.

Hi Brijesh,

I want to use both PSDKLA and PSDKRA on each core as both can be run together on TDA4VM Edge AI - and also for my project needs.

Thank you

Hi Neeraj,

ok, but i guess you want to use CSIRX module from PSDKLA, correct?

Hi Brijesh,

Sorry for confusion in SDK. Confirming I use "PROCESSOR-SDK-LINUX-J721E — Linux SDK for DRA829 & TDA4VM Jacinto Processors"

Now could you please point me sample code for Mipi, USB Camera interface, more specific to QR reader? Since I build and load entire SDK I have access to modify kernel/user code.

Along with this I also need a way to Enable WiFi, access GPIO, UART/tty, I2C, SPI interfaces on the same board.

Thank you

Could you please share me link having example code for all the interfaces?
I am using "ti-processor-sdk-linux-j7-evm-08_02_00_03-Linux-x86-Install" SDK on TDA4-VM Edge AI board.

Thank you
