Dump firmware

[y0d4]

Hi, is it possible to dump existing fw of this device?

save as file is unavailable

Not sure why the save file button is greyedout.

Can you please open the JLink Commander and try the savebin command as mentioned in the link.

hm, i try but nothing happen, no error, nothing..

C:\Program Files (x86)\SEGGER\JLink>JFlash.exe savebin C:\1\test.bin 0x0000000 0x100

C:\Program Files (x86)\SEGGER\JLink>

p.s: i have nrf52840-mdk dongle

if no error is given, then you should have a file saved test.bin in the given location where the 0x100 bytes of memory starting at 0x0 should be dumped

no error and no file... :S

I have never seen this kind of behavior before and on my desk, it clearly creates the file.

Which version of jlink are you using?

[y0d4]

hum, then what do you suggest to try?

I have never seen this before, so I do not know, maybe try some other drive other than C:.

This seems to be an issue with the Segger JLink.exe driver.
