SK-AM62: BLUETOOTH AND WIFI

Hi Veerapandiyan,

what is your goal here? Enable and use both BLE and WiFi at the same time?

Regards, Andreas

Hi Andreas,

Yes. same time enable BLE and Wifi. How to enable?

Hi Andreas,

How to enable UART1 and UART2 i want BLE is connected UART1 and UART2 how to enable.

Thanks Regards,

How to enable UART1 and UART2

To enable UART(s), basic how-to info can be found here:
https://dev.ti.com/tirex/explore/node?node=A__AIGDKkj3W5pn5WQK5DA3Lg__linux_academy_am62x__XaWts8R__LATEST&placeholder=true

Note that for SDK 9.0, there's an additional step that may be needed, which is increasing the Kernel CONFIG_SERIAL_8250_NR_UARTS from 4 (default) to something higher, also see here:

2.I referred datasheet is mentioned UART2 is WIFI interfaced i enable UART2 and WIFI enable pin is active high but WIFI not connected.

Where did you see it? If I look at the SK-AM62 schematic block diagram, only UART1 is connected to thee WiLink-8 WiFi/BLE module:

Also for WiFi, you don't need any UART working at all. It will go all over the MMC2 interface. Basic WiFi bringup info can be found here:

Hi Andreas,

Please refer schematic diagram is connected Bluetooth module is connected to UART1 below the image page no-17 SK-AM62x-E3

AM62x SK EVM User's Guide Link : https://www.ti.com/lit/ug/spruj40c/spruj40c.pdf?ts=1695275180347&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FSK-AM62 block diagram is connected UART1  and MMC2 i will understood.

Below screeshot is connected to wilink module is UART2 page no - 13.

Ok, let me go see what the disconnect is, looks like the documentation is out of sync.

Hi Andreas,

Ok. I will wait.

Thanks Regards,

Veerapandiyan V.

Hi Andreas,

Any Update. I will wait for your reply.

Thanks Regards,

Hi Veerapandiyan,

I looked into this some more, and it looks like there was a change in terms of UARTs used for BT as the SK-AM62 HW design evolved. Different setup will be needed depending on what exact board revision you have.

Hi Andreas,

I have Used E3 version attached image below:

how to enable Bluetooth tell me

Hi Andreas,

Wifi is working that e2e forum https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1250811/am625-wl1837mod-is-not-registered-in-processor-sdk-linux-am62x-version-09-00-00-03

I want to enable Bluetooth only you update and help Bluetooth only

Thanks Regards,

Great, thanks for confirming.

We already determined we will need to use UART1 for BLE. So what you'd need to do next is get the schematic for that specific(!) revision of your board (E3) from the product folder at https://www.ti.com/tool/SK-AM62 (look for "Design File Package"), and trace where the signals go. IIRC there are some muxes you need to switch/control to route those signals correctly from the AM62x SOC all the way to the WiLink8 module, which can all be done via device tree settings. Same as for configuring/enabling the MAIN_UART1.

Also we are experiencing a very high support load at the moment, so I need to prioritize some other support cases for now so it'll take me until next week to get back on this and perhaps run some experiments to prove it out if time allows. In the meantime I'd encourage you to look through the forum here, issues regarding building older SDKs have been asked on several occasions already.

Regards, Andreas

Hi Andreas,

I have enable UART1 is not working Bluetooth. I attached UART1 Configuration below:

Hi,

as indicated earlier it'll take me until next week to look at this again. Please allow some time for that.

Regards, Andreas

Hi Andreas,

Ok. I Still wait.

Hi,

I'm still not able to get to it due to other priorities; it'll may take another week or so.

Regards, Andreas

Hi Andreas,

I want argent Andreas Bluetooth function. I chat with one half months not solving problem how to fix and send your Bluetooth working video.

Thanks Regards,

 wifi is working fine. but hypervisor is disbled how to run same time hypervisor and wifi tell mee.

Hi Veerapandiyan, as per my other post there is a very large backlog of other rather complex/urgent support work. I'm currently needing to prioritize other work items.

Hi Andreas,

Its nice to see you back in office, i can understand the backlogs. We are in middle of signing an important project with the client we are finalizing the end details. It would be really great if you can answer our query within a day or two. We have to show our capability of porting the Bluetooth. Everything is hanging on a loose thread. Please put our problem on priority. Hoping to see your reply asap

Thanks Reagrds
