FreeMaster can not modify variables

[Dong_Luo]

Hello,

My current project's variables, which are put at the TSA table, can be updated runtime via Freemaster UART communication, however, when changing these variables, it reported "Error 0x80000089 (Access to target resource is denied)."

The modifying mode for the variable is "Any value within proper limits".

Hello Dong Luo,

there are two macros to declare a variable in TSA table, please check which one you are using:

• FMSTR_TSA_RO_VAR - for READ-ONLY variables (possibly your case?)
• FMSTR_TSA_RW_VAR - for READ-WRITE variables

In case this does not help, you can also disable the all access checking by setting FMSTR_USE_TSA_SAFETY to 0.

Regards,
Michal

Hello Michal,

Thanks for your reply. My case is using FMSTR_TSA_RO_VAR so these variables can not be modified by FreeMaster. It works after changing to FMSTR_TSA_RW_VAR.
