IAR Information Center for STM8

[EWSTM8-641, EW23488] On some rare occasions a crash in the ST-LINK debugger could occur which give the message "Unknown exception in processor (#P1)".

New features

It is now possible to set option bytes from your source code. See the C-SPY Debugging Guide for more information.
The debugger can now attach to a running target. This feature is available from the Project menu.

Program corrections

[EW24000] Register bit SEG07 is incorrectly placed in register LCD_PM1 instead of LCD_PM0 for STM8L052xx, STM8L152xx, and STM8L162xx devices.
[EW23920] The 8-bit bitfield DMA1_C3PARH_C3M1ARH_bit in the header files (.h) and SFR files (.sfr) for some devices contains 16 bits (PA8-PA15 and M1A8-M1A15) instead of 8 bits. Affected devices are STM8L051F3, STM8L052xx, STM8L151xx, STM8L152xx, and STM8L162xx.

New features

New Predefined Macros
Two new predefined macros have been added, execUserExecutionStarted and execUserExecutionStopped. They are called when the debugger is about to start/resume execution and when it has stopped. The macros are not called when performing a one-instruction assembler step, i.e. Step/Step Into from within the assembler window.

Program corrections

[EW23747] The definition of ADC1_TRIGR4 has been corrected for STM8L151C6 and STM8L152C6.
[EW23148] The "Go to definition" function could sometimes fail.

Program corrections

[EW22939] The TC and RXNE were switched in UART3 status registers for the STM8S20x devices. This is now corrected.
[EW23195] Corrected bits in the Timer 3 registers for the STM8L10x devices.
[EW23416] Corrected bits in the ADC1_CR2 register for the STM8L151x8 devices.

Program corrections

Missing bits in the RTC registers added for the STM8151x, STM8L152x, and STM8L162x devices.
[EW22583] The checksum calculation went wrong using some devices due to an error in the flash programming. This is now corrected.
[EW22383] The driver installation could claim that the current language was not supported at the end of the installation. This is now corrected.
Executing a single step on a halt, wfi, or wfe function left the debugger in a locked state. This is now corrected.

Program corrections

The IAR C-SPY Debugger fails to stop execution after stepping over a C statement if the first instruction of the statement is a call to an extracted common subroutine. Such subroutines are generated when compiled using the high size or high balanced optimization settings (-Ohz and -Oh). This is now corrected.
