1.IAR 1.30 download problem
I used ST-Link V2 to download the STM8L project code of IAR 1.30 project, but found that it could not be downloaded. The Debug Log of IAR software showed:
An error occurred while retrieving GDI features: gdi-error [40201]
According to the search results on the Internet, the IAR debugger-support-files file was missing. Uninstalling and reinstalling the IAR 1.30 software solved the problem.
2. IAR 3.10 download problem
IAR 3.10 cannot download the STM8 code and prompts the error SWIM PROG error [42008]: Attempt to write to protected area. In fact, the STM8 chip is write-protected. Here we will remove the write protection.
(1) Click [ST-LINK] and select [Option Bytes].
(2) A pop-up window appears, click [OK];
(3) The [Option Bytes] pop-up box appears, click [OK];
(4) It will prompt you to remove the write protection. Finally, you can download the debugging code.
