Hello, I noticed an example configuration for SD card reader + ESP32 support
has been recently added to NuttX (esp32-devkitc:mmcsdspi). This configuration
defines the option "CONFIG_ESP32_SPI_SWCS", which I suppose should control the
CS (chip select) pin by code/software. Whenever a command is t

Not always. It depends on the pins used. You can check
arch/xtensa/src/esp32/hardware/esp32_pinmap.h, if you use the set of
pins defined there then you don't need ESP32_SPI_SWCS.

Hello, I’m a newbie to nuttx, I’m using the maix-bit board which has the
k210(RISCV) by ‘sipeed.com’.
I tried to use the examples in the apps folder, but apparently I need to
make the drivers for the K210 board.
Please can I get help on how to make the drivers for a specific board, in
this case t
Hi Kenneth,
Is it the LED example that you commented at LinkedIn? It is important
to always explain exactly what you are trying to do and how you are
trying to do.
If you want add support for LEDs to be controlled by applications you need:
1) map the GPIO pins you are planing to use;
2) Create
Hello to all
I'm developing a Linux-like GPIO system and I need to reach arch
definitions (for example STM32_GPIOE_BSRR) in a portable way
Obvious choice is arch/board/board.h but in the case of STM32, there's not
an elegant way to reach arch/arm/src/stm32/stm32.h from there
What would be the pr
Hi,
I'm trying to test WiFi support on ESP32 DevKitC (I used wapi config) and it
does not seem to work. I get this:
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:2
load:0
It could be because there are some issues with getting the paramters from
the flash. Please try disabling Save Paramters from the Wifi Configuration
menu.

Thanks, now the interface appears.
What functionality is currently supported? Can I connect to WPA2 AP? Can I
create an AP?
Also, I'm trying to scan and I get:
nsh> wapi scan wlan0
ioctl(SIOCSIWSCAN): 25
ERROR: Process command (scan) failed.
Thanks,
Matias

Basically you can just check the commands in the wlan_ioctl function
in esp32_wlan.c to see what's implemented. But not much going on
there for the moment.
You can connect to access points. Commands are given in the README.txt file
wapi psk wlan0 mypassword 1
wapi essid wlan0 myssid 1
You can als
Thanks, I was looking at the DevKitC readme which does not have these
instructions.
I cannot seem to connect though, not sure if it is because my router is set to
WPA2 TKIP+CCMP.
Best,
Matias
