Question about In-Field Update


#1

I use EMX and I am trying In-Field Update.

I have written the test code just like as the tuturial https://www.ghielectronics.com/docs/147/in-field-update

I use GHI’s Tool to produce the ManagedApp.hex. (see picture 1), After connecting EMX I click the “Creat” button and save the ManagedApp.hex in my computer, am I right?

I saved Firmware.hex, Firmware2.hex, Config.hex, Firmware.sig, Firmware2.sig, Config.sig and ManagedApp.hex in SD card, and plug into my EMX board

I have written a button1 handler to implement the IFD function as follow:


        public static void Main()
        {
            ............................................................................
            ............................................................................
            //Button Handler
            InterruptPort IntButton1 = new InterruptPort(EMX.Pin.IO21, false, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdgeLow);

             IntButton1.OnInterrupt += new NativeEventHandler(IntButton_OnInterrupt1);

        }


static void IntButton_OnInterrupt1(uint port, uint state, DateTime time)
        {
            Debug.Print("Button1 Pressed");
            try
            {
                // Initialize System Update, passing in what areas you want to update
                // Optionally select what regions to update
                SystemUpdate.Initialize(SystemUpdate.SystemUpdateType.Config | SystemUpdate.SystemUpdateType.Deployment | SystemUpdate.SystemUpdateType.Firmware);

                // Load in the 1st firmware file
                LoadDataFromSD(@ "SD\Firmware", SystemUpdate.SystemUpdateType.Firmware);

                // Load in the 2nd firmware file
                LoadDataFromSD(@ "SD\Firmware2", SystemUpdate.SystemUpdateType.Firmware);

                // Load in the Configuration file
                LoadDataFromSD(@ "SD\Config", SystemUpdate.SystemUpdateType.Config);

                // Load in your newly created application
                LoadDataFromSD(@ "SD\ManagedApp.hex", SystemUpdate.SystemUpdateType.Deployment);

                // Check to see if you can update
                if (SystemUpdate.CanUpdate)
                {
                    // If we can update, tell the firmware to copy the new files to flash, and restart.
                    // After this restart, your newly loaded firmware files, configuration, and application will be on the board.
                    SystemUpdate.FlashAndReset();
                }
            }
            catch (Exception e)
            {
                throw new Exception("Fail when updating data " + e.ToString());
            }
        }

After rebuilding project and running ok, I pressed button1 and got a window as in picture2
why I can’t updata the "ManagedApp.hex "?


#2

I wonder if you need to specify extension of the files as well.

SD\Firmware.hex

instead of

SD\Firmware

Same for Firmware2 and Config


#3

@ Architect -

Thank you, I have specified extension of the files, und run my project. It seems that only Firmware.hex is updated, and project stopted and gave me the Exception.

I got the debug information as follow:

Hmmm, it’s interesting that the IFU barfs at the last block (block 131/132). On my G120, IFU fails if the array being fed to SystemUpdate.Load() is too small, which usually happens on the final block, since this is where the remainder goes.

http://www.ghielectronics.com/community/forum/topic?id=11482


#5

@ workhard10 -

Hello, it looks like that exception comes from “reading from SD”, check your file name, debug step by step so you can see what file cause exception, not IFU, try another SD card if needed.

In case IFU report the file size too small, it was fixed and be coming at next release.
But right now, you can fix it by make sure that every block (include last block) is >= 46. it is easy by re-define your block size.


#6

@ workhard10 - If it’s the block size problem, another alternative perhaps is to add some dummy print statements in your managed code and vary the length of the string(s) that they print until you find a suitable hex file length that doesn’t make IFU stop. Just conjecture though. I haven’t tried this yet.

If you’ve been following the example, your block size will probably be 10240 bytes. To determine if it’s the length problem, I’d take the modulus [(number of bytes in hex file) % 10240] to get the remainder. If the remainder is less than 46, the length issue may be what you’re encountering.


#7

@ Iggmoe -

thank you for your help! I have checked my software, it seems that it’s my SD card define problem. I have made some changes and now the Firmware.hex, Firmware2.hex, Config.hex, ManagedApp.hex are updated.

but new problem happens, the project stopt. I can see as follow from the Output window:

I thought the borad will be restarted and ran my updated new application. but it stopts now,
I don’t know what’s going on… the the T35 display show me nothing…


#8

2 fotos of my board after updating…

I just updated the same project as the running project

Before updating the project was running well, I could see the leds on my board running


#9

I have used “EMX Updater” reflashed my EMX and tried some times. I find that the program stopts at “SystemUpdate.FlashAndReset();”.


SystemUpdate.FlashAndReset();

It seems that the flash can not be flashed and reseted…

Can you have Cobra/EMX or spider and try the IFU at you kits? to see if the same problem happens?

the follow is the button handler for IFU function:


 static void IntButton_OnInterrupt1(uint port, uint state, DateTime time)
        {
            Debug.Print("Button1 Pressed");


            try
            {
                // Initialize System Update, passing in what areas you want to update
                // Optionally select what regions to update
                SystemUpdate.Initialize(SystemUpdate.SystemUpdateType.Config | SystemUpdate.SystemUpdateType.Deployment | SystemUpdate.SystemUpdateType.Firmware);

                // Load in the 1st firmware file
                LoadDataFromSD(@ "SD\Firmware.hex", SystemUpdate.SystemUpdateType.Firmware);

                // Load in the 2nd firmware file
                LoadDataFromSD(@ "SD\Firmware2.hex", SystemUpdate.SystemUpdateType.Firmware);

                // Load in the Configuration file
                LoadDataFromSD(@ "SD\Config.hex", SystemUpdate.SystemUpdateType.Config);

                // Load in your newly created application
                LoadDataFromSD(@ "SD\ManagedApp.hex", SystemUpdate.SystemUpdateType.Deployment);

                Debug.Print("Flash And Reset waiting.....");

                // Check to see if you can update
                if (SystemUpdate.CanUpdate)
                {
                    Debug.Print("Can Update.....");
                    // If we can update, tell the firmware to copy the new files to flash, and restart.
                    // After this restart, your newly loaded firmware files, configuration, and application will be on the board.
                    SystemUpdate.FlashAndReset();

                    Debug.Print("Flash And Reset");
                }
            }
            catch (Exception e)
            {
                throw new Exception("Fail when updating data " + e.ToString());
            }
        }

the follow is debug output:

Can Update.....



#10

@ workhard10 -

The function is FLASHANDRESET, it means Flash then Reset, :slight_smile: when the board is being programming, it takes (I don’t remember exactly) few minutes. Do not reset by your hand, the board will be reset automatically.

try to update Config or Deployment only first to get completely understand how IFU work then you can try with all.


#11

I mean you won’t see any change in screen even Flashandreset is running. When this function is done, the board will be reset. Flashandreset will take few minutes depends on how big your data is.


#12

thank you!! I try it again!


#13

I know why my In-Field Update was always not successful now.

I have 6 thread tasks in my project, one of the thread tasks is watchdog.

I must stop the watch dog before updating the new application. somethings like as follow:


            // We don't need Watchdog anymore, we have to keep resetting the timeout
            GHI.Premium.Hardware.LowLevel.Watchdog.Enable(GHI.Premium.Hardware.LowLevel.Watchdog.MAX_TIMEOUT);
            WDTCounterReset.Abort();

            try
            {
                Debug.Print("In Field Upfata beginn......");

                // Initialize System Update, passing in what areas you want to update
                // Optionally select what regions to update
                SystemUpdate.Initialize(SystemUpdate.SystemUpdateType.Config | SystemUpdate.SystemUpdateType.Deployment | SystemUpdate.SystemUpdateType.Firmware);

                // Load in the 1st firmware file
                LoadDataFromSD(@ "SD\Firmware.hex", SystemUpdate.SystemUpdateType.Firmware);

..............................................................
.................................................................

                if (SystemUpdate.CanUpdate)
                {
                    Debug.Print("Can updata......... wait flashing and reset");
                    // If we can update, tell the firmware to copy the new files to flash, and restart.
                    // After this restart, your newly loaded firmware files, configuration, and application will be on the board.
                    SystemUpdate.FlashAndReset();

                    Debug.Print("wait flashing and reset ready!");
                }
            }
            catch (Exception e)
            {
                throw new Exception("Fail when updating data " + e.ToString());
            }

            Thread.Sleep(Timeout.Infinite);
