LPC-Link on LPC1788

lpcware · ‎06-15-2016

Using:
- LPCxpresso 4.2.2 registered to 128K (on 2 PC)
- 3 LPC-LINK LPCxpresso LPC11U14 Rev.A
- 3 OemBaseBoard + 5 OemBoard from Embedded artist for LPC1788
- Needs 512K flash option.
- 2 Custom Board with LPC1788.

The main problem is:
"04: Failed to erase flash: EF(9) Flash erase or write operation aborted"
This happens on all the combination of the aboved tools.
Tipically this happen about the 50% of the writing process.
It seems to depend by some "project configuration"on the IDE; if we change project... flashing works; returning to the previous project flashing gives error....
It seems to depend also by the board, changing the board alla works for a certain time.

Sometimes we have other error as "Commit Flash Write"; of "target error" during debug.

FYI: we observe the rate of rise of the percentage on the flash writing phase; if this is high (or become high during the phase) flashing gives error; if it is slow the operation is OK.

Have someone worked seriously with LPCXpresso & LPC1788?? And it works??
There is something to do, to work in an acceptable manner??
There is an IDE with emulator that works better?

So you are using the GUI flash tool, as per...

http://support.code-red-tech.com/CodeRedWiki/GuiFlashProgramming

?

Can you clarify exactly what you are doing in this dialog (which options you have selected) and also turn on the progress log option and send us the log text generated when the tool completes.

Then post the debug log file from when you then launch the debug session after using the above tool.

You also mentioned right at the start of this thread that...

Would it be possible for you to provide two such images (ie one which works, then a second that causes the failure)? Probably the easiest thing to do here would be to take a copy of the project at the point where you see a failure, then modify the original project until it "works".

http://support.code-red-tech.com/CodeRedWiki/CopyingExampleProjects

It would be useful here to get both the linker map file, and also the axf file - assuming that source project cannot be supplied. And this can be done "off forum" if you prefer - just zip the files up and send them to support at code-red-tech.com, with a reference to this forum thread.

If you can send buildable projects, then please see this FAQ for details of how to export them from your workspace...

Next time i will try.

At the moment i have resolved (as said before) simply clicking the "program flash" button, and then retrying "Debug" button; it seems to work always.

And have you tried the tests I suggested back on 9th May yet?

My suspicion at present is that you are putting some code into flash that is destabilising the part, and preventing the debug tools obtaining control when you try to reconnect. Try booting the board into ISP mode, or enabling the "vector catch" functionality in the debug launch configuration, as detailed in the FAQ that I previously pointed you at. Then let us know if either of these allow you to connect to your board.

Note that I have again just run a series of tests here using LPCXpresso 4.2.2, an LPC-Link and an Embeddded Artists LPC1788 board, and see no problems.

As an absolute minimum, if you want any help, then please provide the debug log !

Update:

Today the problem reoccurred; it has been resolved using the "program flash" button (same error) and returning to "debug button" (restart to work).

For the speed, the comparison is made for the same project beetween the correct operation :)(percentage increase slowly) and the bad operation :mad:(percentage increase fastly); maybe the lpclink believe that flash block require no update and skip??

It is good to hear that you are working. However if you want us to try to look into the issues that you have been seeing (including the "slow flashing" you still mention), then please go through the procedure that I previously asked you to and report the results - including providing the debug log.

The other point regarding "slow flashing" is - what is this in comparison to? Did you previously have LPCXpresso/LPC-Link working and flashing at a "faster speed" ?? Remember that LPC-Link is a "cheap and cheerful" debug probe - Red Probe+ will provide a much faster download and general debug performance.

CodeRedSupport

Yesterday the system return to work misteriously, (flashing speed always slow), next time the prbolem will occurs, i will update this post.

Another info:
Sometime when i cant' connect with debugger (bug icon) i can suuccessfully program using the "program flash" (chip icon on lpcxpresso).

In any case i ALWAYS can program the flash with FlashMagic

In the first place, please ensure that you are providing sufficient power to the boards - particularly if you are just using USB. If you are, make sure you are connecting to the correct USB port on the board, and preferably use a powered USB hub rather than just the supply from your PC. Better still, use an external power supply.

Power supply is a particular thing to watch with LPC1788 boards, which often have a big LCD screen to drive too. Please check the Embedded Artists documentation for exact power requirements here.

Anyway, after checking your power, please can you try the following:

[LIST]
[*]Create a new workspace (File -> Switch workspace).
[*]Import the LPC177x_8x CMSIS library project from the LPCXpresso examples subdirectory.
[*]Use the project wizard to create a new LPC1788 "semihosting C project" with the default settings.
[*]Now power down your board, then bring it back up in ISP mode:

[/INDENT]
[LIST]
[*]After selecting the "semihosting C project" that you just created in the Project Explorer view, use the GUI interface to the flash programmer to mass erase the flash (using the options on the "Erase flash memory" tab)...
[/LIST]
[INDENT]http://support.code-red-tech.com/CodeRedWiki/GuiFlashProgramming

[/INDENT]
[LIST]
[*]Now build the "semihosting C project" that you just created, then use the Debug option on the Quickstart menu to program it to flash and start a debug connection.
[/LIST]
Does this then correctly run?

If not, then please provide the debug log...
