Write Flash error PIC24FJ256GB210

[bioelettrico]

Hi, I'm trying to use Ds30 Loader (v 1.5.7-2.2.14) with PIC24FJ256GB210, but I can not write in the Flash.
I receive the following error:

-------------------------------------------------------------------------------------

What can be the problem?
Thank you.

Hi,
What is the output with debug mode enabled?
Please post the boot loader project(zipped).

Hi Mikael, in the meantime I solved....
I  have mistake put several times in the CONFIGx the character "&".
This generated an incorrect value of the "Flash Write Protect" values.

Thank you.

Hi,
Good to hear.

Hi,
Good to hear.

Hi Mikael, the bootloader on PIC24FJ with GUI Loader seems to work fine.
But I would need to change some controls in the GUI (address for programming on RS485 bus with non-standard protocol).
Is it possible to have sources in C#?

Hi,
The source code is not available. If you are willing to pay for it, we can probably work something out. Contact me from https://ds30loader.com
