+
+# Compatibility Concerns
+
+## Changes to Kconfig
+
+The names of some Kconfig settings have been changed to improve the naming
consistency. Here is the list:
+
+| Old| New |
+|:------------------:| -----------------:|
+|LIB_BOARDCTL|BOARDCTL |
+|LIB_CRC64_FAST|LIBC_CRC64_FAST|
+|LIB_ENVPATH |LIBC_ENVPATH |
+|LIB_HEX2BIN |LIBC_HEX2BIN |
+|LIB_HOMEDIR |LIBC_HOMEDIR |
+|LIB_HOSTNAME|LIBC_HOSTNAME|
+|LIB_KBDCODEC|LIBC_KBDCODEC|
+|LIB_RAND_ORDER|LIBC_RAND_ORDER|
+|LIB_SLCDCODEC |LIBC_SLCDCODEC |
+|LIB_USRWORK |LIBC_USRWORK |
+|LIB_USRWORKPRIORITY |LIBC_USRWORKPRIORITY |
+|LIB_USRWORKSTACKSIZE|LIBC_USRWORKSTACKSIZE|
+|LIB_ZONEINFO|LIBC_ZONEINFO|
+|LIB_ZONEINFO_ROMFS|LIBC_ZONEINFO_ROMFS|
+
+When they appear in code, these identifiers begin with a `CONFIG_*` prefix
(e.g., `CONFIG_LIB_BOARDCTL` is renamed to `CONFIG_BOARDCTL`).
+
+All in-tree boards have been updated, but users who maintain their own
out-of-tree boards will have to update all instances of these identifiers.
+
+See PR-4266 https://github.com/apache/incubator-nuttx/pull/4266 and PR-4267
https://github.com/apache/incubator-nuttx/pull/4267 in the main NuttX
repository.
+
+See also PR-820 https://github.com/apache/incubator-nuttx-apps/pull/820 and
PR-821 https://github.com/apache/incubator-nuttx-apps/pull/821 in the NuttX
apps repository.
+
+## Changes to MTD subsystem
+
+MTDIOC_XIPBASE, MTDIOC_FLUSH and MTDIOC_PARTINFO is removed and replace with
BIOC_XIPBASE, BIOC_FLUSH and BIOC_PARTINFO:
+
+* Simplify the general driver(e.g. partition, flt) implementation
+* Reduce the confusion with the same IOCTL in the different layer
+
+See PR-4325 https://github.com/apache/incubator-nuttx/pull/4325
+
+## Changes to Build System
+
+### LD Now Called Through GCC
+
+When building NuttX with GCC toolchains, the linker is now called through
$(CROSSDEV)gcc rather than $(CROSSDEV)ld. This requires all linker options to
be prefixed with `-Wl,` (dash, capital W, lower-case L, comma). All boards in
the NuttX tree have been updated, but any custom out-of-tree boards will need
to apply this change in the relevant parts of their build scripts.
+
+The reason for this change is that GNU Binutils 2.36.x has added new error
checking on command line arguments. This has had the effect that the NuttX
build suddenly broke on host OS distributions that updated to the 2.36.x
release line. Reports included Arch, Manjaro, and Ubuntu. Other host OSes are
likely to be affected as well.
+
+#### Symptoms
+
+Your toolchain and board are affected if you see errors from LD like:
+
+```
+arm-none-eabi-ld: Error: unable to disambiguate: -nostartfiles (did you mean
--nostartfiles ?)
+```
+
+or (following this change in NuttX) errors from GCC like:
+
+```
+arm-none-eabi-gcc: error: unrecognized command line option '--gc-sections';
did you mean '--data-sections'?
+```
+
+#### What to change
+
+The most common change expected to affect most boards:
+
+Change:
+
+```
+NXFLATLDFLAGS1 = -r -d -warn-common
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1)
-T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -no-check-sections
+```
+
+to:
+
+```
+NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common
+NXFLATLDFLAGS2 = $(NXFLATLDFLAGS1)
-T$(TOPDIR)/binfmt/libnxflat/gnu-nxflat-pcrel.ld -Wl,-no-check-sections
+```
+
+If doing a kernel build, you may need changes in your board's
`kernel/Makefile` like:
+
+Change:
+
+```
+USER_LDFLAGS = --undefined=$(ENTRYPT) --entry=$(ENTRYPT) $(USER_LDSCRIPT)
+```
+
+to:
+
+```
+USER_LDFLAGS = -Wl,--undefined=$(ENTRYPT) -Wl,--entry=$(ENTRYPT)
$(USER_LDSCRIPT) -nostartfiles -nodefaultlibs
+```
+
+Change:
+
+```
+$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) --start-group
$(USER_LDLIBS) --end-group $(USER_LIBGCC)
+```
+
+to:
+
+```
+$(Q) $(LD) -o $@ $(USER_LDFLAGS) $(USER_LIBPATHS) $(OBJS) -Wl,--start-group
$(USER_LDLIBS) -Wl,--end-group $(USER_LIBGCC)
+```
+
+Depending on your board's customized build scripts, you may need to look out
for other `make` variables in your board's `Makefile` or `Make.defs`.
+
+Some variables to look for:
+
+- `ARCHSCRIPT`
+- `ARCH_LIBS`
+- `CCLINKFLAGS`
+- `EXTRALINKCMDS`
+- `LDELFFLAGS`
+- `LDENDGROUP`
+- `LDFLAGS`
+- `LDLINKFLAGS`
+- `LDMODULEFLAGS`
+- `LDSTARTGROUP`
+- `NXFLATLDFLAGS1`
+- `NXFLATLDFLAGS2`
+- `USER_LDFLAGS`
+
+Anything that executes LD, such as:
+
+```
+$(Q) $(LD) --entry=__start $(LDFLAGS) $(LIBPATHS) $(EXTRA_LIBPATHS) \
+```
+
+Anything that processes LD flags, such as:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+In general, any command line options destined for LD must be prefixed with
`-Wl,` (dash, capital W, lower-case L, comma) since they are now being passed
through GCC.
+
+#### Examples
+
+Change:
+
+```
+EXTRALINKCMDS += @$(TOPDIR)/syscall/syscall_wraps.ldcmd
+```
+
+to:
+
+```
+EXTRALINKCMDS += -Wl,@$(TOPDIR)/syscall/syscall_wraps.ldcmd
+```
+
+Change:
+
+```
+LDFLAGS += -gc-sections
+```
+
+to:
+
+```
+LDFLAGS += -Wl,-gc-sections
+```
+
+Change:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS) -Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+to:
+
+```
+$(LIBPATHS) "-(" $(LDLIBS) "-)" $(LDFLAGS)
-Wl,-Map="$(TOPDIR)$(DELIM)nuttx.map"
+```
+
+Change:
+
+```
+NXFLATLDFLAGS1 = -r -d -warn-common
+```
+
+to:
+
+```
+NXFLATLDFLAGS1 = -r -Wl,-d -Wl,-warn-common
+```
+
+Change:
+
+```
+ifeq ($(CONFIG_CYGWIN_WINTOOL),y)
+LDFLAGS += -Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" --cref
+else
+LDFLAGS += -Map=$(TOPDIR)/nuttx.map --cref
+endif
+```
+
+to:
+
+```
+ifeq ($(CONFIG_CYGWIN_WINTOOL),y)
+LDFLAGS += -Wl,-Map="${shell cygpath -w $(TOPDIR)/nuttx.map}" -Wl,--cref
+else
+LDFLAGS += -Wl,-Map=$(TOPDIR)/nuttx.map -Wl,--cref
+endif
+```
+
+Also, if you have assigned the LD variable, it would need to change as well:
+
+Change:
+
+```
+LD = $(CROSSDEV)ld
+```
+
+to:
+
+```
+LD = $(CROSSDEV)gcc
+```
