Hello,

is there a way to preselect the "Auto" button in NetDCU-USB-Loader from the command line or via a registry entry? Or from the NBI File?

Martin

Hello,

is there a way of reading the versions (build numbers) of NBOOT, EBOOT and the WEC 2013 Kernel Image Version Number? Some File? Registry entry? NDCUCFG?

Thanks in advance,

The problem is that the aforementioned DeviceIoControl returns failure after some runtime (with many transfers prior to failing). I cannot provide the exact value or if the function is ok again in the next call. It occurred in an end user application and I have only the information that the communication failed while communicating with at least 2 different devices (of different kind) on the bus.

I would like to know if the named issues fix any problems that may occur after some runtime or if the issues just fix things that would fail immediately. Or in other words: I want to know if the problem may be solved if we update to the latest kernel and drivers. Because if you didn't fix anything which is a problem after some runtime, the fixes are not relevant for us. (Updating the kernel in the field cannot be done).

Of course there could also be some electrical problem in the attached hardware, but when the device is powered off and on again, the problem is gone, which makes software suspicious.

Does the NI2C allocate memory in any form to do a transfer? If yes, then the "small memory leak" issue may also have an influence and the problem may be solved by using V2.20 or higher (issue 0003112).

I want to avoid an kernel update as long as I am not entirely sure the Update fixes the problem.

Hello,

we have at least 2 efusA9 Boards with the WEC 2013 V1.80 Firmware which experienced problems with the I²C (NI2C) after a long (probably several weeks) runtime.

Boards with V2.30 and newer have not yet shown such behavior. We are using I2C_B with no IRQ but write and read (with repeated start condition).

There are several Issues concerning NI2C (FSiMX6 Changelog.txt):

- 0003298: [NI2C] Setting values of drive strength and pull up doesn't work - resolved

- 0003294: [NI2C] Bus toggle doesn't work correctly if it is lock up - resolved

- 0003074: [NI2C] Repeated start does not work - resolved

- 0003040: [NI2C] Sometimes occurs an exception while boot process - resolved

- 0002935: [NI2C] efusA9: I2C_B_IRQ is configured as output - resolved

My question is: Are these issues addressing problems which may occur after a long runtime?

Here is a snippet how we use the driver:

Kind Regards

The Kernel 1.80 has been released today with the WDOG Fix.

Hello,

this is just a bug report:

NDCUCFG Version 61 crashes on EFUSA9 V2 with the "device enum" command on both, the command line and the serial port.

Exception 'Data Abort' (0x4): Thread-Id=01900006(pth=c08a83b8), Proc-Id=018e0006(pprc=c08a46f8) 'ndcucfg.exe', VM-active=018e0006(pprc=c08a46f8) 'ndcucfg.exe'

Hello,

I tested WEC2013 1.50 by just watching the System Properties / Memory Tab and also notice the approx. 12KB/h increase of Program Memory in use:

I will keep the system running without any external interaction and report my observations.

I just had a look at the EC2013 Roadmap which notes the fix for the WDOG issue in the 1.70 release planned for February 2016.

We do not have the time to wait until then.

Is there any workaround (HW or SW) which I can apply on my own?

Hello,

thank you for the Information.

Is there a way to disable the watchdog? I do not need it, we have our own watchdog on the carrier board.

I provide the following Information as it might help your colleagues finding a solution:

After one of my boards was reset by WDOG, the board behaved strange: Yesterday in the evening the USB Keyboard was working but, today in the morning it didn't work anymore. I left the Board powered up over the night. I reset the board with the reset button (connected to RESET IN). My custom application started up as usual. The Serial Debug Port shows the following messages upon every access of the I2C B Bus:

Start condition or Repeated Start can't be launch.NI2C3: The bus idle.
Start condition or Repeated Start can't be launch.NI2C3: The bus idle.
...

The only devices connected are one PCA9555 and one TMP175.

My oscilloscope shows continoues LOW for I2C_B_DAT and continous HIGH for I2C_B_CLK.

This error state is preserved even after hardware resets!
After power down and power up the I2C is working again.

I am using 3 threads with priorities 255 (with quantum 2), 252 (with quantum 5) and 250 (with quantum 0).

The resets occured after several days of continous operation, up to more than a week. The one I monitored with the serial debug port resetted after about 30 hours.

Hello,

I am observing occasional resets of the EFUSA9 Solo CPU Board. Occasional means: after 3 hours, after 1 day and after nearly 2 weeks.

I have been observing the serial debug output. There is no error or crash printed. The output from the rebooting board reveals the reason for the restart: WDOG or Watchdog

How can i find out what causes the "WDOG" to reset the board? My 5 V supply (up to 3 A) measures 4.983 V, the supply of the TFT display measures 3.232 V.

I am using the NSPI, NI2C, Ethernet and a LVDS attached display NEC NL10276BC13-01C which is powered by the EFUSA9.

Hello,

I think there is an issue because the decrease in available physical memory can be observed with no application running, with no user interaction and no network cable connected.

Just boot up the board, open the Memory tab in the Control Panel/System and wait. The number of Program Memory in Use will increase by about 12 kB per hour.

Hello,

I am investigating a decrease of the "Available Physical Memory" returned by GlobalMemoryStatus() of about 200 KB/day in Windows Embedded Compact 2013 (efusA9 V1.60 - Firmware, Build: Oct 16 2015/20:01:55, EFUSA9 V3 Solo; LVDS attached Display)

Although 200 KB/day sound not that much it is too much for a system that has to be available 24/7.

I have hunt down the problem to an Operating System Issue: When I open Control Panel/System/Memory and observe the "Program Memory in Use" for several hours, it shows the same leak rate of about 200 KB/day (12 KB in 90 minutes). This test is done without our custom application running, with no network connection and no USB devices.

I therefore suspect something in the OS or one of the drivers.

Is there any chance to find out the leakee?

Thanks!
Works perfectly in WEC2013 F&S 1.40 on efusA9

Here is the NDCUCFG command sequence:

reg open \SYSTEM\GWE\
reg set value Animate dword 0
reg create key ANIMATE
reg open ANIMATE
reg set value Frames dword 0
reg set value DelayMilliseconds dword 0
reg save

Attention to all developers:

QueryPerformanceCounter() on efusA9 on WEC2013 F&S Version 1.40 seems to return a per-core counter, resulting in start time larger than stop time when a thread which measures short amounts of time runs on one core to get the start time and then on the other core to get the stop time.

• Are there any plans to fix this?
• How is GetTickCount() implemented? Does it use QueryPerformanceCounter() (or its time source) for the tick count? Or does it return a some OS counter?

Hello,

I downloaded the SDK (ndcucfg_lib.h and ndcucfg_lib.lib). I get this error at link time:

1>------ Build started: Project: mcu-fw-x, Configuration: Release FSiMX6 WEC2013 ------
1>LINK : fatal error LNK1113: invalid machine type 0x1C2
========== Build: 0 succeeded, 1 failed, 1 up-to-date, 0 skipped ==========

Seems as if the LIB is not intended to be used with FSiMX6 WEC2013.

I got a new SDK and then could implement using the I²C. Now I use the I2C2: device on the efusA9 (I2C_B).

By the way: The Document WINCE_FSiMX6_DeviceDriver_eng.pdf contradicts with the actual registry settings for the Touch drivers.

The Touch drivers have "I2C3:" set for the I2CDevice registry value.
The PDF document states, that the Touch drivers use "I2C2:" and one should use "I2C3:" for other purposes.

By the way, if anyone needs it: Here are my settings for the NEC NL10276BC13 TFT Display (6,5", 1024x768, LVDS):

reg open \drivers\display\lcd
reg set value Mode dword 100

reg set value PONCflPow dword 0

reg save
reg open \drivers\display\lcd
reg enum
reg open \drivers\display\lcd\Mode100
reg enum

OK, i found out how to use BL_CTRL:

The PWM value of BL_CTRL is the "contrast voltage". So I added these lines to my Display Config script for NDCUCFG:

reg set value ContrastEnable dword 1
reg set value ContrastValue dword 0
reg set value ContrastFreq dword 20000

The Frequency on my oscilloscope actually is 50 kHz.

contrast set 0 -> 99,x % duty cycle (full brightness)
contrast set 4095 -> 0 % duty cycle (completly dark)

• Which values are allowed for the ContrastFreq?
• How can I set the contrast from my application without spawning a NDCUCFG process?

Hello,

are the BL_CTRL and VCFL_ON signals of the efusA9 already implemented in WEC2013 F&S Kernel 1.40? Are the signals usable even if the display is connected to the LVDS connector?

I would like to switch the display on and off and to dimm the backlight darker and brighter from our application.

I already checked the Changelog and Roadmap but did not find anything about them. I already checked the device driver documents but I did not find information dedicated to the efusA9.
