Because:
* A raw binary doesn't make sense for sim, where ./nuttx is
a host OS executable.
* It breaks test builds on macOS, where native objcopy
is not available.
* The appropriate size of stack varies among archs.
E.g. for 64-bit sim, 2048 is way too small, especially when the task
happens to use host OS functionalities.
I plan to allow an arch provide its own default.
* I plan to use this to replace hardcoded "STACKSIZE = 2048" in APPDIR.
This reverts commit b9ace36fcc.
This change was added by PR 625 but has a serious logic flaw. It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:
else ifeq ($(WINTOOL),y)
DEFINE = "$(TOPDIR)/tools/define.sh"
INCDIR = "$(TOPDIR)/tools/incdir.sh" -w
This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined. As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.
Necessary for dlfcn etc on ESP32, which has separate memory regions
for instruction and data.
known issues/todo
* consider something similar to dual heaps for PROTOECTED
* consider to adapt binfmt as well
boards/z80/ez80/z20x/configs/w25boot/defconfig: Increase size of serial Tx buffer.
boards/z80/ez80/z20x/src/w25_main.c: Add some fflush() in necessary places. Greatly improves the usability of the UI.
boards/z80/ez80/z20x/README.txt: Trival update to README
drivers/serial/serial.c and tcdrain.c: Correct some typos.
- boards/z80/ez80/z20x/scripts/z20x_*.linkcmd: Reduce from 4 to 1 wait state. That i sufficient because of the slow clocking of the eZ80F92
- boards/z80/ez80/z20x/src/w25_main.c: Replace CRC algorithm with simple, less time consuming check sum.
- boards/z80/ez80/z20x/configs/nsh: Rename the nsh_ram configuration to just nsh
- boards/z80/ez80/z80x/configs/hello: Add simpler program to make debugging the loader easier.
I skipped the following files because they were not simple.
I'll create separate PRs.
arch/xtensa/src/esp32/esp32_cpustart.c
arch/xtensa/src/common/xtensa_abi.h
boards/xtensa/esp32/esp32-core/include/board.h
Also, I skipped the following files and directories because
they looked too huge and/or foreign.
arch/xtensa/include/esp32/tie.h
arch/xtensa/include/xtensa/xtensa_corebits.h
arch/xtensa/src/esp32/hardware/
arch/xtensa/include/esp32/tie-asm.h
arch/xtensa/include/esp32/core-isa.h
arch/xtensa/include/xtensa/core.h
I also fixed a few "is is" style typos when unwrapping long lines.
arch/z80/src/ez80/ez80_timerisr.c: Correct a mismatch between the programmed reload value and the timer input clock frequency.
arch/z80/src/ez80/ez80f92.h: Correct error in timer input clock divider: Bits 2-3, not bits 3-4.
boards/z80/ez80/z20x/src/w25_main.c: Correct an uninitialized return value; private function was not declard static.
boards/z80/ez80/z20x/src/w25_main.c: (1) Correct size comparison typo: Should have been >= not != (2) Fix sizeof(): Was ugetting the sizeof the pointer instead of the sizeof the pointed at structure. (3) Improve some comments.
boards/z80/ez80/z20x: Increase RX buffer size to 4Kb, reduce BAUD to 2400 in w25boot configuration
arch/z80/src/ez80/ez80_serial.c: Reduce Rx FIFO trigger level for eZ80F92 to 1 so that will respond more quickly to incoming data.
boards/z80/ez80/z20x/src/w25_main.c: Improve user interface.
There is still an error occurring while downloading Intex HEX files to FLASH. That is unrelated to this and appears to be a problem libs/libc/hex2gbin/lib_hex2bin.c
fix the following warning:

Adds -fno-strict-aliasing to ARCHOPTIMIZAITON definition for all sim Make.defs file. This is constistent with the setting used in the Make.defs file of all other architectures and should eliminate the build test warnings:
arp/arp_arpin.c: In function 'arp_arpin':
arp/arp_arpin.c:136:13: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_sipaddr, &dev->d_ipaddr);
^~~~~~~~~~~~~~~~~~~~
arp/arp_format.c: In function 'arp_format':
arp/arp_format.c:96:3: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
net_ipv4addr_hdrcopy(arp->ah_dipaddr, &ipaddr);
^~~~~~~~~~~~~~~~~~~~
And similar warnings from icmp/icmp_input.c, and tcp/tcp_send.c. -fno-strict-aliasing i required for a warning free build of NuttX code since there is use of punned pointers.
