Question: how to compile the "device_program" in ATK R1.60 ?
Context: "i.MX Platform Advanced Tool Kit (ATK) Standard R1.60"
I'm working with a legacy product based on a i.MX27 board.
As I understand the ram kernel mx27_nand.bin
may be obtained from this ATK R1.60.
As the old gnu toolchain is not available anymore
(ref. doc. "ATK Reference Guide Standard Version.pdf")
I'm working with a recent toolchain for gnu arm.
I modified accordingly the file "rules.make":
------rules.make----------
CC = arm-none-eabi-gcc
AS = arm-none-eabi-as
LD = arm-none-eabi-ld
NM = arm-none-eabi-nm
OBJDUMP = arm-none-eabi-objdump
OBJCOPY = arm-none-eabi-objcopy
READELF = arm-none-eabi-readelf
RM = rm -f
RN = mv
CP = cp
TOPDIR = $(shell pwd)
BIN = arm-none-eabi-objcopy
LIBDIR = "/usr/lib/gcc/arm-none-eabi/5.2.1/"
SHELL = /bin/sh
CFLAGS = -Wall -Wstrict-prototypes -Wno-trigraphs -nostartfiles -O0 -nostdlib \
-static -feliminate-unused-debug-symbols -fno-strict-aliasing -fno-common \
-pipe -fno-builtin -g -mapcs -mlittle-endian \
-msoft-float -mfpu=vfp
------rules.make----------
where the modifs are for CC & other variables and the option -mfpu=vfp for the floating point unit.
When I try to compile with:
"make MCU=mx27 flashlib FLASH_TYPE=NAND"
I get the following errors:

-------
It seems like the ram kernel should link with the std libc, but on the compile flags
we have "-nostartfiles -nostdlib", hence not the std libs asked...
My question is: what am I missing as a library to link to this ram kernel ?
