Compiler/TMS570LC4357: if the add_device() function can be called more than one time?

Tool/software: TI C/C++ Compiler

hello

I called the add_device() function to build a simple file system in my software， we saved the data in the internal flash.

During execution, my program will be hot reset many times.

I find, sometimes, after the hot reset, it can destroy the file system and I can't open the file successfully.

can you tell me if the add_device() is allowed to be executed many times by the hot reset? if it is not allowed, how to resolved it ?

Hello,

Several things can cause the system reset:

1. OSC fail (configurable)

2. PLL slip (configurable)

3. VMON out of the valid voltage range

4. Watchdog exception

The reset source is stored in SYSESR register.

The hot reset is caused by the watchdog.

Hi Waite,

There are several libraries for Hercules devices: SafeTI Diagnostic Library, F021 Flash API Library, Cortex-R4 CMSIS DSP Library. Can you please let me know which library is add_device() from?

Hi Waite,

Do you mean the add_device() in the RTS (runtime support library) located in compiler folder?
