Hi,

In the TFA v2.2 code base, the file "lib/xlat_tables_v2/xlat_tables_core.c" has the implementation for function "xlat_tables_map_region()". The implementation for this function is changed in TFAv2.2 (compared TFAv1.5), with addition of function "xlat_clean_dcache_range()".

Due to this addition, my earlier* working platform on TFAv1.5, is hanging here. If the function call for the function "xlat_clean_dcache_range()", is comment, then the platform works well.

Code snippet: static inline __attribute__((unused)) void xlat_clean_dcache_range(uintptr_t addr, size_t size) { if (is_dcache_enabled()) clean_dcache_range(addr, size); // On commenting this line, my platform works fine with TFAv2.2 }

Please share your views on what could I be missing here.

Thanks.

Regards Pankaj

*Earlier raised patch for this platform was not merged due to review comments are not disposed-off in time; and TF-A got migrated from github to gerrit.
