Pe Micro, preserve memory bug.

christofferjärl — Mon, 17 Feb 2020 12:34:01 GMT

Hi!

Is this "preserve memory range PE Micro" bug solved yet?

Or is there any other working solution?

Just installed S32DS 2.2, and fully updated (also all PE Micro up to date) but no luck! (Same on S32DS-18)

Same problem on 2 computers Win7 64bit...

Tested with both OpenSDA and Multilink Universal.

I'm using the other SDK EEPROM example. (Referred in top post)

Everything seems to work, except when you use "preserve memory range", the pegdbserver always crashes, and can not load/flash the target successfully.

With OpenSDA:

Hi,

as far as I know - PE Micro won't fix it. From PE Micro's understanding this is not a bug. The memory is successfully preserved when DFlash is not partitioned as a backup for EEEPROM - which is technically correct - but useless.

In my opinion (as a regular user) - the memory should be also preserved if it is already partitioned. I understand that it's little bit tricky - Dflash is not directly accessible when partitioned as EEEPROM backup. The only way how to Read/Write data is through FlexRAM. But I think that it is still doable by Flashing algorithm - for example by skipping erase from 0x1000000 to 0x1000FFFF or reading data from FlexRam - Erase flash - re-partition it and write data back to FlexRAM.
