SK-TDA4VM: Expected features for next SDK release.

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM

Greetings,

As next Edge AI SDK for SK-TDA4VM is not released yet (current version is 08.00.01), please let me to point out what features would be nice to see:

1. Added support for OV5647 double camera (rPi connector), including range estimation example.

2. Added support 5GHz (20/40/80/160 MHz WB) mode for Intel 9260 Access Point and initial support of 6 GHz for Intel AX200/210.

3. Added support for booting from OSPI SPL UBOOT and load Linux from NVMe SSD.

4. Fixed I2C5 external connector (rPi) issue (change I2C config from MUX to direct link).

5. Added support of h.264 hardware encoder for GStreamer.

6. Switched LAN to WLAN packet route processing to R5F core.

This is a note, not a question.

Thanks,

Alexey

    Thank you Alexey!

    I have relayed your suggestions to the developers of the Edge AI SDK. We will not be able to integrate the features for the next 8.1 release as it is coming up very soon, but we will keep your suggestions in mind for future releases.

    Regards,

    Hi Alexey, 

    Thank you for the note! It is not clear to me if you have already added above features, or requesting TI to provide them.  Can you please clarify what's your objective with above note?

    Hi,

    No, I do'nt. But I know that all cases are in a process of implementation at TI's side. So here are some comments:

    1.  Range estimation can be implemented using TDA4VM's Depth and Motion accelerator. Initial command support of OV5647 is avalable on Linux kernel side.

    2. Some info from archlinux.org:

    "

    Apparently with the special country code 00 (global), all usable frequencies in the 5Ghz band will have the no-ir (no-initiating-radiation) flag set, which will prevent hostapd from using them. You will need to have crda installed and have your country code set to make frequencies allowed in your country available for hostapd.

    Note that recent Intel devices have a Location-Aware Regulatory (LAR) feature, which ignores the userspace regulatory database and instead deduces the regulatory region by listening to other nearby access points. This means the devices will not transmit on any 5 GHz frequencies until they have first seen other access points on the 5 GHz frequency bands, preventing any 5 GHz transmission at all in many cases. Older kernels had an option to disable this which was removed in 2019 due to it causing the firmware to crash. Since this removal, Intel cards supporting LAR can no longer be used as access points in the 5 GHz band.

    "

    3.  It must be a way to install all files in OSPI using UBOOT from other shared soucre in a LAN using tFTP protocol and confiugre UBOOT environment to access ext4 file system on NVMe.

    4. SK-TDA4VM board doesn't have I2C5 MUXing device to utilize MUX feature. This makes connection failed.

    5. This is a planned feature for implementation in TI's roadmap.

    6. This is a planned feature for implementation in TI's roadmap.

    Regards,

    Alexey

    This is TI's product.Objecive is to add such features by default, as they meant to be a part of your product, and add related documentation to support this.
