The format specifier for the "unsigned int" variable is documented as
"%d". However, it should be "%u". Thus, fix it.

|
=====================
|
|
|
|
Each conversion specification consists of:
|
|
|
|
* leading '%' character
|
|
* zero or more flags
|
|
* an optional minimum field width
|
|
* an optional precision field preceded by '.'
|
|
* an optional length modifier
|
|
* a conversion specifier
|
|
|
|
Flags
|
|
-----
|
|
|
|
'space'
|
|
fill up with spaces to reach the specified length
|
|
|
|
\-
|
|
left justify
|
|
|
|
\+
|
|
add sign field of decimal conversion
|
|
|
|
#
|
|
convert to alternative form
|
|
|
|
* prepend 0 to octal output
|
|
* ignored for decimal output
|
|
* prepend 0X to hexadecimal output
|
|
|
|
0
|

Length modifiers
|
|
''''''''''''''''
|
|
|
|
The optional length modifier specifies the size of the argument.
|
|
|
|
no modifier
|
|
bool, enum, short, int are passed as int
|
|
|
|
%h
|
|
convert to (unsigned) short before printing.
|
|
Only the low 16 bits are printed.

Conversion specifiers
|
|
'''''''''''''''''''''
|
|
|
|
Conversion specifiers control the output.
|
|
|
|
%d
|
|
signed decimal
|
|
|
|
%u
|
|
unsigned decimal
|
|
|
|
%o
|
|
unsigned octal
|
|
|
|
%x
|
|
unsigned lower case hexadecimal
|
|
|
|
%X
|
|
unsigned upper case hexadecimal
|
|
|
|
The floating point conversion specifiers are not implemented:
|
|

|
* %a
|
|
* %A
|
|
* %e
|
|
* %E
|
|
* %f

Characters
|
|
----------
|
|
|
|
%%
|
|
a '%' character is written
|
|
|
|
%c
|
|
prints a single character
|
|
|
|
%lc
|
|
**not implemented**
|
|
|
|
Strings
|
|
-------
|
|
|
|
%s
|
|
prints a UTF-8 string (char \*)
|
|
|
|
%ls
|
|
prints a UTF-16 string (u16 \*)
|
|
|
|
Pointers
|
|
--------
|
|
|
|
%p
|
|
prints the address the pointer points to hexadecimally
|
|
|
|
%pa, %pap
|
|
prints the value of a phys_addr_t value that the pointer points to
|
|
preceded with 0x and zero padding according to the size of phys_addr_t.
|
|
The following types should be printed this way:
|
|
|
|
* fdt_addr_t
|
|
* fdt_size_t
|
|
