Hi all,

in our application, we use a Atmel SAM4LC8 that we would like to re-program ("update") in the field.
We use a Segger Flasher ARM to initially program the micro controller.
In the software, the security bit is set. After this, the only way to re-program the device is sending an "Erase" instruction.
When we send an "erase" instruction in Atmel Studio 6.2, we can re-program the device without any problems.

Now we would like to re-program the device with J-Flash (later with the "AUTO" function), but it seems that it can only be programmed / erased when a connection to the device is made.
It is not possible to connect (Target-> Connect) to the device when the security bit is set.
Is there a work-around for this problem? Is there a way to send the erase instruction without verification?
We have to regularly update our products in the field, so in the future we want to do this with the Flasher ARM Portable.

Thanks in advance

Hi Erik,

that is correct, after setting the security bit we cannot longer use the "Connect..." function in J-Flash.

please do add me to the software and update notifications, so we can implement this in the future as soon as it is available.

We really would like to use the stand-alone "Flasher Portable" to do in-the-field updates.

For now, we'll just have to do it by hand.

Thanks for your reply.

Is there already an update about this issue?
We really need the erase function now because sometimes, a DUT in a testfixture needs to be re-programmed after a fix in the pcb.
It's annoying to have an additional programming environment at our PCB assembly house just to erase the DUT's before we can program them again.
