When converting winIDEA workspaces from older versions (e.g. 9.17.xx) to a newer one, or using the same initialization sequences (INI files), which worked with old winIDEA versions but not with the newer ones, you might encounter errors such as:
E 021 S_NNN: Callpoint failed: ..\<yourINISequence>.ini
The most likely reason this callpoint fails is that the INI sequence specifies a command that was deprecated between the two winIDEA versions.
When importing an initialization sequence into a newer winIDEA version, always inspect the INI file and, if necessary, substitute the deprecated commands with the actual ones.
For example, if an S (write) command was used in
the old winIDEA version: S REG_NAME L 0xDABAD000,
it should be replaced with the A (write) command to work with newer winIDEA versions: A REG_NAME L 0xDABAD000
