Started a new SimpleIot/Zephyr project targeting several MCUs:
This project is an example of how you can use the Zephyr Workspace T2 star topology where you can define custom apps and boards, and pull in Zephyr as a dependency. Not much here yet other than build, but more to come soon …
This is awesome, can bring power of SIOT to MCUs bridged by Zephyr.
Found a neat little tool that is now integrated into simpleiot/zephyr-siot:
If you get a crash, you can quickly locate source code by:
py) [cbrake@quark siot]$ west dbt addr2src 0x400fc9f1
Reading symbols from /scratch/simpleiot/zephyr-siot/siot/build/zephyr/zephyr.elf...
0x400fc9f1 is in uart_esp32_irq_rx_ready (/scratch/simpleiot/zephyr-siot/modules/hal/espressif/zephyr/esp32/../../components/hal/esp32/include/hal/uart_ll.h:295).

291 // When using DPort to read fifo, fifo_cnt is not credible, we need to calculate the real cnt based on the fifo read and write pointer.
292 // When using AHB to read FIFO, we can use fifo_cnt to indicate the data length in fifo.
293 if (rx_status.wr_addr > rx_status.rd_addr) {
294 len = rx_status.wr_addr - rx_status.rd_addr;
295 } else if (rx_status.wr_addr < rx_status.rd_addr) {
296 len = (rx_status.wr_addr + 128) - rx_status.rd_addr;
297 } else {
298 len = fifo_cnt > 0 ? 128 : 0;
299 }
This is a good example of how west can be extended with additional commands.
