bluetooth choppy sound ubuntu 20.04 and 18.04

Earsistemas — Thu, 25 Mar 2021 21:00:05 +0000

Ubuntu 20.04 , Up Core Plus, I have followed all instrucctions from wiki pages (Up kernell and Wifi/BT firmware), but the sound is chopped all the time in the bluetooth devices. Using HDMI, sound output is ok.
I have tried PulseAudio latency offset, many pairings with differents bluetooth devices and all possible configurations, but always the same: it connects but the sound is choppy. The A2DP configuration is possible, but the HSP/HFP is not available. Please, any help will be wellcome. Thanks

UP Core Plus I2S Audio support - Linux

Jaimin_Thakkar — Tue, 10 Nov 2020 12:08:54 +0000

Hi Team,

We are planning to use I2S (AVS_I2S2_*) from a 100pin docking connector for interfacing with audio codecs in our product.
Can we get any support/reference implementation of the codec integration with Linux?
What are the changes (BIOS, IO mixing, machine driver, etc) needed for the integration?

Thanks,
Jaimin

Could not see any visible networks on UP core plus after installing Ubuntu 18.04

Shm — Tue, 27 Oct 2020 12:35:59 +0000

Hello,

I have a UP core plus board. I followed** https://wiki.up-community.org/Ubuntu_18.04** to install Ubuntu 18.04 on the board. I also installed Ubuntu kernel 5.0.0 locally from debian packages.Then installed the Ampak firmware for WiFi and Bluetooth locally from debian package. So basically I set up my board as said in the wiki link.
Now I can see wlan0 interface when I execute iwconfig. But when I do iwlist wlan0 scan , there are no scan results.
There are no visible networks in the WiFi settings menu.
As per the link , the WiFi should be up and running if we follow all the steps mentioned in the link.But in my case I could not see any networks around me.
Please help!!!!

Does some know the mapping of the i2c buses on Linux.

/sys/bus/i2c/devices/ shows 10 i2c buses:

$ ls -l /sys/bus/i2c/devices/
total 0
lrwxrwxrwx 1 root root 0 Jan 20 17:33 i2c-0 -> ../../../devices/pci0000:00/0000:00:16.0/i2c_designware.0/i2c-0

The 100-pin connector has I2C0, I2C1 and I2C6. But what are their mapping to Linux buses?

Thanks you.

OV5647 (Raspberry Pi camera integration) supported???

Zoromoth — Sun, 16 Feb 2020 01:34:36 +0000

I have a raspberry pi with the OV5647 sensor module. The standard linux drivers contain a built ov5647.c Is this supported by up core plus? I had this question since the board has 2 Mipi csi camera lanes. Is the standard prebuit driver in linux:

a. Smart enough to figure out which lane to use?

b. Is tje driver even compatible with up core plus.

Any help will be greatly appreciated...

Thanks and Regards,

failed to install Ubuntu 16.04 for Up Core Plus

hgemini — Thu, 29 Aug 2019 08:02:53 +0000

Hello,
I tried to install Ubuntu 16.04 for Up Core Plus (Atom® x5-E3930), but failed even to load install. Though I watched install menu, when loading installer, the following message shows up and returns back to boot.

Regarding "TPM error", by disabling secure boot in BIOS it doesn't show up anymore.

I tried to search the error "Couldn't get size: ...", and it seems to be related with secure boot,
but I cannot find any solution.

Giving me any advices are really helpful.

Best regrads,
