A20 / Re: Wired and Wireless ethernet problem A20 Lime2
« Last post by sdrollinger on Today at 01:17:30 AM »
Sorry guys, this is not what's happening. When the the eth0 is connected everything is still working fine.  The only problem we are experiencing is querying MySQL from the wlan interface if the eth0 is also connected.  I will post the my.cnf file as well.

Here is the route information

A64 has WiFi/BLE on board, shielding it in metal box will disable these features

Hi Michael,
the link to your modified example for Olimex EVB is dead, can you make it available again?

> What baud did you try?

115200, i am sure baud rate is not the problem here, because when TRRS jack is used serial console works properly, problem (strange chars) comes only when TRS jack is used.

It could be possible that the TRS jack used here is slightly off in physical dimension from the standard.

Any way as i am able to use console properly using TRRS jack, no issues now for me and Thanks Olimex for the reply.
JTAG / Re: U-boot update to EmCraft i.MX6ULL Borad using OLIMEX ARM-USB-OCD-H
« Last post by LubOlimex on March 19, 2018, 02:00:22 PM »
The orientation of the small cable looks weird to me but I can't be sure where the ticks of the connectors are. Check how this cable looks here:



So double check the hardware connections again. Maybe use a multi-meter tool and set it to short-circuit check mode, disconnect the 10-20 adapter from ARM-USB-OCD-H and insert a pin at the end of the small cable and place one multimeter electrode on the soldering at 10-20 adapter (under the connected 0.05" cable) and the other on the pin that you inserted in the connector at the end of cable. This would help you identify where is pin #1 after the cable.                                               

I assume that you power the target board from another location, if you don't, please power the iMX6ULL board from another source.

Also I saw this guide for the board:


Notice that there are visitable links - that contain the needed cfg files, make sure to use the cfg files provided by the manufacturer (they also seem to use Olimex ARM-USB-OCD-H as seen in one of the links here: https://www.emcraft.com/som/imx6ull/mfg-jtag.cfg).

Since EmCraft seems to be familiar with ARM-USB-OCD-H, it might be a good idea to also drop them an e-mail, maybe they would know more about the proper software and hardware setup.

Best regards,

Both TRS and TRRS jacks should be ok. When you use TRS jack, the MIC input of the laptop is shorted to GND. When you use TRRS, the MIC in goes to the headphones (handsfree) MIC. The jacks we tested here are fine. TS and TRRRS are not ok.

> serial port was abusing me ;), all strange chars.

What baud did you try?

> As the TRS jack was inserted, 2 ring ones might have got shorted here & caused the problem.

I doubt it but in the world of electronics anything is possible.
A20 / Re: No way to download official images
« Last post by LubOlimex on March 19, 2018, 09:26:15 AM »
You didn't mention what image exactly you need. Nor what board you have.

If you need a specific image drop me an e-mail at support@olimex.com and I would think of way to receive the image that you need (as mentioned at the very bottom of the wiki article)

<<< As i mentioned, there are even FREE ways of hosting.

Ok, as soon as you receive the image that you need, please feel free to host it and provide links in your blog or in this forum, so others can download it from your links.

Best regards,
