printf String formatting broken

[FranzKnut]

Hi!

I am currently developing an application for nrf52832 and am using the uart module with retarget.c for output over uart via printf().

Now a few days ago I added FDS flash storage support and all of a sudden the String formatting using additional parameters for variables (apart from type) stopped working.

For example if I previously invoked

printf("%04X", 1);

I got "0001" as output but doing so now will result in "4X".

Similarly,

printf("%2.5f", 1.0);

will now lead to ".5f".

When deleting all of the additional parameters and only keep the type (%X, %f) everything works as expected.

Any help is much appreciated,

Julian

I finally figured it out!

For Segger Embedded Studio in Project Options: Code -> Printf/Scanf when "Printf Floating Point Supported" is set to "No" the code behaves as depicted. Changing it to "Float" got printf back to working as expected.

I do not know to which compiler settings this corresponds but it solves my problem.

Thanks, Julian
