problem when copying in RAM

alexismercier — Tue, 16 Jul 2013 13:04:44 GMT

hi everybody,

I'm trying to save some parameters in Flash memory bu I think Ihave some problems with copying in RAM ( see my attached program).

It seems to work but the two first digit of my numbers are invisible when I use the debugger.

thanks for help

I guess you didn’t select “refresh flash when halting” option.

When you debug code with hardware, go to Hiwave debugger menu “MultilinkCyclonePro”, “Debugging Memory Map”. In the open dialog, select the memory section that need refresh, click “Modify/Details” button, in the new dialog, check “refresh flash when halting”.

Hi Jun Zhang ,

thanks for the speed of your answer.

refresh memory map is already checked in my parameters
as you can see there are only the two last digits of my numbers.

Hi,

Please close memory window in the debugger before you start the application, or else the window will read flash periodically, this operation may influence the flash programing in the application.

In addtion, did you check those values being programed are correct before they are programmed actually? I mean those variables named carac, carac1,...in your code.

Best Regards.

Best Regards
