A20 / Re: 40-PIN RIBBON CABLE for A20-Olinuxino-Lime2

« Last post by LubOlimex on June 18, 2018, 09:01:21 AM »

So my question is: can I connect CABLE-40-40-10CM directly in GPIO-1, GPIO-2 or GPIO-3?

Yes. It can be connected to any of the 40-pin GPIO rows. Including the LCD connector. You might need to perform some wire tracing to get the proper layout.

Code: [Select]

One of pin connectors is 0.1 step and the another is 0.05?
Yes, exactly. One side of the adapter is 0.05" and the other is 0.1". Just don't forget the cables.

Strange. Maybe the TCP IP stack used as a basis for the example has some trouble with certain telnet clients.

BTW you have two times Windows 7 with same procedure. Maybe #3 is Windows 10?

The A20-OLinuXino-LIME2-UEXT is useless to me because i cannot connect it directly to GPIO extension headers: GPIO-1, GPIO-2 or GPIO-3!

So my question is: can I connect CABLE-40-40-10CM directly in GPIO-1, GPIO-2 or GPIO-3?

One of pin connectors is 0.1 step and the another is 0.05?

A20 / When will T2 production boards be available for purchase?

« Last post by g_allbee on June 16, 2018, 10:12:17 PM »

Specifically, I am looking forward to replace the A20-SOM-IND with the T2-SOM-IND with ALL components rated for -40C.

Please advise on your plan for the first production release.

Thank you,
Gary

TERES DIY Laptop / Re: Teres 1 Battery not charging?

« Last post by Asara on June 16, 2018, 07:34:23 PM »

Okay, got the laptop running.

Process: Unplug the battery from the A53, put the power cable in, get to the boot screen.  quickly unplug the cable, attach the battery, and then turn on the laptop again.

Thanks a ton to both adj__ and diego71 in #olimex for the help!

Hooked up the battery to a multimeter to check the voltage (as advised by the IRC channel) and it seems to not be a problem with the battery.

New Product Ideas / Re: RISC V possible in TERES? or any Olimex board?

« Last post by JC on June 16, 2018, 07:32:40 AM »

I've been chatting with a few CEOs, and the next step they are envisioning is a RISC-V headless computer, such as a SBC or router.

Hi, I'm Palmer from SiFive.

The FU540-C000 is capable of running standard Linux graphics stacks.  We regularly give demos of it running X via an AMD graphics card attached over PCIe, you can see one at FOSDEM where I gave the whole presentation off a HiFive Unleashed.  The RISC-V Linux port is upstream, and while all the drivers necessary for a full system aren't upstream yet we're working on it.

Micro Semi has a board available that's more tightly integrated than the setup we've demonstrated <https://www.crowdsupply.com/microsemi/hifive-unleashed-expansion-board> https://topicmixbd.com/2016/07/18/side-effects-of-phen375-and-what-to-do-to-avoid-them/ In theory you could build a single board that integrates the FU540-C000 with some low power FPGA that would fit into a laptop form factor, but nobody has demonstrated this yet. Quantities are a bit of a sticking point, and unfortunately it's difficult to discuss these things in a public forum.  If you're seriously interested in doing a RISC-V laptop then I'd love to chat so we can figure out how to move forwards.  Feel free to send me an email, or if you're going to the RISC-V workshop we can chat there.

The cheap really doesn't have any graphics.

ESP32 / Re: ESP32-EVB Rev D - ethernet: no ip, no connection

« Last post by LubOlimex on June 15, 2018, 04:53:35 PM »

No boards from revision D2 had been released. The latest hardware revisions is D1.

Do not add R58 since this change is related to the other change of D2 revision (MCP2551 to MCP2562). This is not needed if your board is hardware revision D1. Furthermore these changes are not related to the Ethernet but to the CAN.
