Remove I/O format specifier macros from bootloader
Closed, ResolvedPublic
Actions

Description

The 8-bit format specifier macro types (e.g. PRIu8) requires the C99 I/O format support to be enabled, otherwise the usage
of these macros results in undefined behaviour. TF-M uses the newlib-nano standard library implementation which by default
does not support these format macros.

  • Remove the format specifier macros used in the formatted input/output functions.

Yes, updating both spm_api.c and tfm_nspm.c to use #ifdef instead of #if for evaluating the macro TFM_PSA_API can help resolve the compiler error in mbed-os. This change ensures compatibility with both cmake-based builds (where the macro is defined using the -D option) and mbed-os (where the macro is defined using #define).
