v0.1.3

For the Seeed XIAO ESP32S3 (8 MB flash) and an x86_64 Linux PC:

• esp-sdr-multiapp-v0.1.3-xiao_esp32s3.bin: multiapp, with MCUboot and every app on its FAT volume.
• libEsdrSupport-v0.1.3-ubuntu24.04-x86_64.so: the SoapySDR module for the board's osmosdr app (driver=esdr), built on
  Ubuntu 24.04 for SoapySDR ABI 0.8 and libusb 1.0. Elsewhere, build it from
  apps/osmosdr/soapy.
• esp32s3-esp-sdr-v0.1.3.svd, esp32c6-esp-sdr-v0.1.3.svd: Espressif's SVDs with the radio
  registers this project documents (doc/undocumented-registers-*.md), for debuggers.

gqrx

1. Flash, with the board in download mode (hold BOOT while plugging it in, or run usj on the
   shell of a running esp-sdr app):

   esptool --chip esp32s3 write-flash 0x0 esp-sdr-multiapp-v0.1.3-xiao_esp32s3.bin
   

2. Load the plugin: SoapySDR loads the modules in the directories SOAPY_SDR_PLUGIN_PATH names.

   mkdir -p ~/.local/lib/esdr && cp libEsdrSupport-v0.1.3-ubuntu24.04-x86_64.so ~/.local/lib/esdr/
   export SOAPY_SDR_PLUGIN_PATH=~/.local/lib/esdr
   

3. Start osmosdr on the board, which reboots into it (again after every power cycle);
   SoapySDRUtil --find=driver=esdr then lists it:

   printf 'app run osmosdr\r' > /dev/serial/by-id/usb-Zephyr_Project_ESP-SDR_multiapp_*
   

4. Run gqrx from the same shell. In its I/O device configuration: device string
   driver=esdr,soapy=1, input rate 250000 (the most USB full speed carries).

On Ubuntu, apt install gqrx-sdr soapysdr-tools brings gqrx and SoapySDR. Without root, the PC
needs udev rules for the board (USB vendor 2fe3), for example in
/etc/udev/rules.d/70-esp-sdr.rules:

SUBSYSTEM=="usb", ATTRS{idVendor}=="2fe3", MODE="660", GROUP="plugdev", TAG+="uaccess"
SUBSYSTEM=="tty", ATTRS{idVendor}=="2fe3", MODE="660", GROUP="dialout", TAG+="uaccess"
ATTRS{idVendor}=="2fe3", ENV{ID_MM_DEVICE_IGNORE}="1"

The other apps: app list and app run <name> on the board's USB shell
(apps/multiapp/README.rst).

v0.1.2

For the Seeed XIAO ESP32S3 (8 MB flash) and an x86_64 Linux PC:

• libEsdrSupport-v0.1.2-ubuntu24.04-x86_64.so: the SoapySDR module for the board's osmosdr app (driver=esdr), built on
