Hello Mike,

That error indicates that bootloader successfully programmed the user application to the flash memory, but it failed to see the user application execute and connect via the USB.

You could be receiving that error either because the bootloader application doesn't have the correct value for USER_APP_ADDR in usbcfg.h. Ensure the bootloader has been built and loaded using the 4000 value.

Another reason that can happen is if the user program hasn't been linked for a base address of 4000. This adjustment is done using the linker configuration within the tools you are using for building your firmware.

Let me know if you have any further questions.

thanks for your answer

my problem not solved.

I use LPC1788 microcontroller and in bootloader program i changed

#define USER_APP_ADDR0x00004000
#define USER_APP_MAX_SZ0x00080000

so after that in DZX USB Workbench , in Device Information has written USBBootloader NOTsupported .

is it important?

In Bootloader tab in DZX USB Workbench , in Hardware Boot Information there is these Specifications:

user application address   0x00004000

user application max size  512.00 KB

write buffer size   4.00 KB


Now when the Request User Application is running , the USB connection Disconnected .

How can I solve it?

I really need it.



thanks

I checked your mentions and they are correct.

when user application start address in bootloader  program and user program are same , when Request User Application is running device disconnected.
when they aren't same for example user application start address in  bootloader  program is 2000 and in user program is 4000 , when Request User Application is running ,  the error  " An error has occurred during the update " . " Details :The device has failed to execute user application" occur.
I've really confused.

Hello Mike,

Our apologies for the delay as our office is only open Monday-Friday.

Just a little bit more information about your setup may help. What hardware are you using? An evaluation board? Also, which version of Windows are you doing this testing with?

Also, when the device is running the demo application and it is disconnected, is it connected within Windows? As in is there a popup appearing that is saying "Device Not Recognized" from Windows taskbar or is it just not connecting within the DZX Workbench?
