I also tried adding an extra 10uF capacitor to the 3v3 reg's output, made no different. I tried adding hacking i n`esp_wifi_result!(esp_wifi_sys::include::esp_wifi_set_max_tx_power(8))?;` (`8` is the lowest power setting) into `wifi_start()`...

Well, getting to this point was a bit of a challenge:  I'll report back with findings now that I'm able to flash, and connect a debugger.

Seems like when it gets stuck, it gets stuck like this: ``` (gdb) info frame Stack level 0, frame at 0x3fc91ec0: pc = 0x4201b7c4 in esp_hal::critical_section_impl::multicore::ReentrantMutex::lock (src/lib.rs:420); saved pc =...

here's what it looks like with `wifi-logs' enabled, when it fails: ``` INFO - esp-wifi configuration Config { rx_queue_size: 5, tx_queue_size: 3, static_rx_buf_num: 10, dynamic_rx_buf_num: 32, static_tx_buf_num: 0, dynamic_tx_buf_num: 32,...

It seems that the crash is occuring in the code for `register_chipv7_phy_init_param`, see above stack trace. For good measure, I erased the entire flash, after reading that the RF calibration...

@JurajSadel Please can you re-test your board and a) cold-boot it a few times, while monitoring the output of the CP2102 UART port. b) reboot it a few times, using...

I tested the same exact code on a board with a different design I made which uses the exact same regulators, capcitors, inductors, power supply scheme and so on and...

Here's a fresh install of the ArduinoIDE and the WifiAP example, it runs just fine.  Also, with the arduino I2C communication to the M10Q UBlox GPS at 400,000kbit works...

> Hi @hydra, sorry for late reply. Sure, I can reopen, however, our time is limited and it looks like a weird issue. I can't say right now, when someone...

In my case, since I have the same issue when powering the MCU directly from bench PSU, which can easily handle any transients, and added extra capacitance, and the MCU...
