Dec 04, 2008  I am developing with an ARM 7 core, and have been able to read memory, get device i.d, test speed with the SEGGER tools, but not program in spite of having a valid licence key for j-flash ARM.

Protected FLASH Pages with Processor Expert Failed Programming with protected FLASH If I try to re-program the protected bootloader with Segger J-Link (both in CodeWarrior and Eclipse/KDS with GDB), then the download silently fails. The effect is that somehow the application on the board does not match what it should be. Looking at the Console view, it shows that erase has failed (but no real error reported):-(: Jlink: Failed to erase sectors 0 @ address 0x00000000 (Algo135: Flash protection violation.

Erasing The Segger J-Link features a very fast programming. Part of that speed is that the Segger firmware checks each FLASH page if it really needs to be programmed, and only then it erases and reprogrammed that page.

So downloading twice the same application actually will not touch the FLASH memory at all. Additionally, it does not do a complete erase of the device: it only programs the pages I’m using in my application. The advantage of that is first speed. And it does not erase the application data I’m using in non-volatile memory (see ““). However, sometimes I really need to clear all my data in FLASH too, and then I need to erase all my FLASH pages on the device. Segger has product named ‘J-Flash’ which is used to Flash and Erase devices outside of an IDE. There is a free-of-charge ‘Lite’ version available for download from Segger.

So I need to use a different tool to unlock and unprotect my device: the J-Link Commander.

Unlocking and Erasing with J-Link Commander To unlock the device, Segger has a utility named ‘J-Link Commander’, available from. The binary is ‘jlink.exe’ on Windows and is a command line utility.

Unlocking and Erasing with J-Link Commander Summary In order to re-program the protected FLASH sectors with Segger J-Link, I need first to unlock and mass erase the device. For this, there is the J-Link Commander utility which has a command line interface to unprotect and erase the device. For erasing only, the J-Flash (and Lite) is a very useful tool, especially to get a ‘clean’ device memory. To me, the Segger way and tools are very powerful.

In this case, things are very flexible, but not that obvious. So I hope this post can help others to get his device unlocked and erased. Happy Erasing
