The component st_size of struct stat is of type off_t. Depending on the system printing it it with %ld leads to a warning:
tools/mkimage.c:438:54: warning: format '%ld' expects argument of type 'long int', but argument 5 has type 'off_t' {aka 'long long int'} [-Wformat=] 438 | "%s: Bad size: "%s" is not valid image: size %ld < %u\n", | ~~^ | | | long int | %lld
When comparing an off_t value to a 32bit integer we should not convert to uint32_t but to off_t which may be wider.
