JTAG / ARM-USB-OCD-H Windows 10 64 bit Serial port driver
« Last post by ghng@element14.com on June 18, 2018, 02:58:22 PM »
Dear Sir,

Customer is using Windows 10 64 bit and has followed the below steps to install ARM-USB-OCD-H Serial port driver but not able to install. It has some error and not able to install USB Serial Converter B and shows OLIMEX ARM-USB-OCD-H (COMx) under Ports (COM & LPT)
https://www.olimex.com/forum/index.php?PHPSESSID=hdfbb58sl6856ukqu833t6t8m3&action=printpage;topic=5636.0
We have tried OLIMEX-FTDI-drivers-2-12-04 and latest 64 bit VCP drivers from FTDI website but it is not able to install.
http://www.ftdichip.com/Drivers/VCP.htm
Please advice where to download the working serial port driver for Windows 10 64 bit.
Thank you.

PIC / PIC-P67J60 demo. Build from sources.
« Last post by ffomich on June 18, 2018, 01:43:49 PM »
Hi,
1. I try to build original demo project with MPLAB X IDE 4.20 & XC8-v1.45 compiler.

Build process exits with error:"../Configs/HWP OLIMEX_P67J60.h:1662: error: (103) #error: "HI TECH not supported."

in file HWP OLIMEX_P67J60.h pragma #error fires
Code: [Select]
#elif defined(OLIMEX_P67J60) && defined(HI_TECH_C)
#error "HI TECH not supported."

What does mean HI_TECH_C?

2. Next I try to build the same project with MPLAB X IDE 4.20 & C18-v3.47-lite compiler.

Build output
Code: [Select]
PIC-P67J60_demo\Source\src\TCPIP\Demo App\UARTConfig.c:246:Error [1300] stack frame too large
Fix: Change #define XMODEM_BLOCK_LEN 64u//128u

Build output
Code: [Select]
BUILD SUCCESSFUL
Write hex file into the board via PIC-KIT3. Reboot.
There is no COM port output, TCPIP Discoverer App can't find device...

Does anybody have experience of porting demo project to MPLAB X & CX8 compiler?

Oh, that's a bit disappointing.

Maybe try linux-sunxi.org - check whether it's intended to be done on their site first then consider their ML.

Perhaps also the U-boot ML if it is indeed sitting in U-boot.

hmm... actually you probably do need to know where it is when shut down (U-boot or some kernel loop).  (Reading code will show this.)

Someone may have useful suggestions or you may even be able to pay someone in the project(s) to do it.

> Can I do that safely without the battery? It's annoying to plug it in and out all the time or to hold it carefully while not taped into place.

The laptop would not boot without battery connected (only on external power supply). It needs the battery to be connected.

Inspect the connections around the main board and the power supply, make sure that these are according to the assembly instructions.

You can connect a serial console to the main board for debugging purposes but if no LEDs turn on then it is probably a major powering problem and console wouldn't show anything anyway.

I disconnected and carefully reconnected all cables on the photo, but this did not solve the problem.

PIC / Re: PIC-P67J60 demo. No Telnet connection.

Telnet via Putty is from Windows7 too.

Here is dump when I try to open Telnet connection to IP_address

Connection opens correctly.

I asked on armbian forum and this is their answer:

https://forum.armbian.com/topic/7481-a20-som-wake-up-from-nmi_n/

the problem is "already implemented in the legacy/BSP stack. Since mainline u-boot and kernel were made from scratch rather than by porting the Allwinner code, this functionality and many other things were not added."

so now im looking how can I implement this on mainline, but really does not know where to start.

Any alternative to wake up from suspend/hibernate would be usefull as well.

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

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?
