Before performing a FLASH download, winIDEA verifies if the Entry point address specified in the Symbol file (ELF file) matches the Application start address specified in the first valid RCHW record of the download image. If this doesn't match, FLASH programming is rejected and a warning is shown:
It is recommended to follow these steps:
Perform the following steps to find the entry point specified in your Symbol file:
1. Open Debug / Configure session / Applications / App / Symbol files.
2. Right-click on the Default elf file and select Dump ELF. The generated file is automatically opened in a text editor.
3. The Entry point address is displayed in the top section of the file.
If multiple .elf files are used in your application, only the Default file for debugging (as selected in Debug / Configure Session / Applications / App / Symbol Files) is considered by the Security checker.
1. Prior to FLASH programming perform a download in Demo Mode.
2. Use the Load Map to inspect the boot record (RCHW) locations as specified in the TRM of the selected SoC.
3. At the first location which contains a valid boot tag, inspect the subsequent 4 byte aligned location for the Application start address.
If you are confident that your device will boot properly (e.g. the entry point address is specified elsewhere, such as a bootloader defined in a separate .elf file), you can disable the Security checker by changing the following settings:
1. Open Hardware menu / CPU Options / Debugging.
2. Uncheck option Check if program entry point is reachable.
3. Set the option If device is about to be programmed to non-destructive state to Allow programming.
