[SOLVED] [JLinkScript] Error using division "/" operator inside script

godmode · May 7th 2020, 3:17pm

Hello,

I can not use simple division inside the script though documentation say it is supported.
Im using version v6.72b.

What am I doing wrong?

Script:

C Source Code

U32 test;
// end variable definitions
test=10/5;

JLinkGDBServer output:

Source Code

ERROR: Error while evaluating J-Link script file: Error while compiling. Line 334, column 14:
test=10/5;
^
Internal error: Compiling "/" operator. Unsupported operand type combination.
Failed prepare script file

Hello,

Thank you for your inquiry.
/ is and was never supported in JLinkScript files.
Could you point me to the documentation you are referencing? It should be corrected.

To do divisions in the JLinkScript you would need to work with the >> operator.

Best regards,
Nino

Documentation:
segger.com/downloads/jlink/UM08001

Paragraph 7.13.5.1 Supported Operators

Operator >> does only 2^n divisions/multiplications.

Hi,

Yes that documentation is not correct and will be fixed.
Sorry for the confusion.

On the surface yes, you can still write helper functions that do any kind of division with >>.
Every CPU is in its core binary and can still do any division with only >>, right?

For examples see stackoverflow or similar resources.

Best regards,
Nino
