Interpreting HEX dump of nv-memory

Elias Zimmermann

Other Parts Discussed in Thread: CC2541

Hello,

since we have unexpected behaviours in a few of our cc2541 - remote controls until we reprogramm the device, we check the flash memory.

Could you help interpreting the the hex dump of nv memory?

As described in xcl file:

BLENV_ADDRESS_SPACE_START=0x7E800 and

BLENV_ADDRESS_SPACE_END=0x7F7FF

How could I find out the latest user-specific nv memory entries (several items)?

how could I find out the latest bonding information?

For example:

:10E80000000010000000000000000000F000080000

Hi Elias,

I am not sure we can help you with this, but I have notified the HID team.

Could you elaborate a bit more on the problems you have?

Cheers,
Fredrik

Hi Fredrik,
we have a rare issue that a remote control (master/central) isn't able to pair / bond with the slave / peripheral. Even when erasing existing bondings on runtime, we won't get up the connection.
Resetting the device doesn't help. Only reprogramming the whole flash solves the problem.

Maybe some nv space gets corrupted when a reset occures while we were writing to it.

Elias,
Do you have a sniffer log or similar that can help us understand what is going on?
