How to get NuttX RTOS working on old ESP32-Devkit with 2MB SPIFLASH
After compiling and flash NuttX with wapi example:
$ ./tools/configure.sh esp32-devkitc:wapi
$ make -j flash ESPTOOL_PORT=/dev/ttyUSB0
I got this error:

xtensa_dump_task: 2 100 4032 1336 33.1% nsh_mainIt is happening because the MTD partitions are located at OFFSET+SIZE that went over the 2MB Flash:
CONFIG_ESP32_STORAGE_MTD_OFFSET=0x180000 CONFIG_ESP32_STORAGE_MTD_SIZE=0x80000 ... CONFIG_ESP32_WIFI_MTD_OFFSET=0x280000 CONFIG_ESP32_WIFI_MTD_SIZE=0xb0000
See 2MB means 0x200000 then the partitions are going beyond that.
An option to fix it is reducing the partition size and moving the WIFI_MTD_OFFSET to below 0x200000:
CONFIG_ESP32_STORAGE_MTD_OFFSET=0x180000
CONFIG_ESP32_STORAGE_MTD_SIZE=0x10000
...
CONFIG_ESP32_WIFI_MTD_OFFSET=0x190000
CONFIG_ESP32_WIFI_MTD_SIZE=0x10000
Now everything is working as expected:

</html> The header order matter
I was having a nasty error when adding W5500 for ESP32S2:
board/esp32s2_w5500.c: In function 'up_enable':
board/esp32s2_w5500.c:139:13: warning: implicit declaration of function 'ESP32S2_PIN2IRQ'; did you mean 'ESP32S2_PERIPH2IRQ'? [-Wimplicit-function-declaration]
139 | int irq = ESP32S2_PIN2IRQ(GPIO_W5500_INTR);
| ^~~~~~~~~~~~~~~

board/esp32s2_w5500.c:135:13: note: declared here
135 | static void up_enable(const struct w5500_lower_s *lower, bool enable)
After spend much time trying to fix it I looked the esp32s2_gpio.c and decided to follow the same header files order, then it worked:

I’m testing the TTGO_LORA32 board (sch here: https://raw.githubusercontent.com/LilyGO/TTGO-LORA32/master/schematic1in6.pdf) with NuttX RTOS and noticed the `sx127x` app is not working with default LoRa Modulation, but at least I got it working with FSK modulation:

Update:
I discovered an interesting fact (that at least happens for TTGO_LORA32 board) :
If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=3 the sx127x app doesn’t work on LoRa mode (-m 0), but works on FSK mode (-m 1). If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=2 the app will work fine for LoRa and FSK mode, but not for OOK. If CONFIG_LPWAN_SX127X_MODULATION_DEFAULT=1 none mode will work.
NuttX Binary to Test Particle Photon board
A NuttX user reported an issue when using Particle Photon board: https://github.com/apache/incubator-nuttx/issues/6938
Then I decided to test it and discovered that some recent modification damaged that board configuration and decided to test an older version that I knew was working.
I converted my nuttx.bin to text (using base64) and created a gist with it. Then you can test yourself:
Download “nuttx_base64.txt”: https://gist.github.com/acassis/4479c13e029415cd05a4b52493f1da52
$ cat nuttx_base64.txt | base64 --decode > nuttx.bin
Confirm the file was created correctly:
$ md5sum nuttx.bin 56f9b321ca946f092e89f42723a0cea3 nuttx.bin
Press the RESET and SETUP buttons of your board, release the RESET and keep SETUP pressed until the LED start blinking on yellow color, then release it as well.
Now that your board is in DFU mode you can flash it using DFU command:
$ sudo dfu-util -d 2b04:d006 -a 0 -s 0x08020000 -D nuttx.bin
We will need a router configured with SSID: DLINK and password: dlinkphoto to test this firmware. It will connected on your board and will assume the fixed IP 192.168.0.16. You can telnet to this IP and get the NSH terminal working over telnet.
