Reboot device (xiao esp32s3) when node.activateOTAA()

[ezefferth]

Hello, I'm trying to use a simple example from this lib, but something got wrong. Months ago, I used this lib and there was not any problem with from that, but recently I used starter example or others, and, the step from node.activateOTAA(), rebooted my device, and started again from radio.begin() > radio.beginOTAA(...) > and it always reboots when it reaches step activateOTAA. I don't know what's hapening. I'm trying to put activateOTAA in a loop, but it always reboots, so, this does not stay in anything. I see it trying to connect and join OTAA from chirpstak, but it always loops. The error from my console is:

Hi @ezefferth,

My first guess would be some small mistake in your code, or maybe a slight hardware error. However, just the reset message of the ESP32 isn't going to help at all.

Can you include your code, properly formatted in a code-block, and logs using the DEBUG_PROTOCOL flag? That will likely help finding a clue to what the problem would be.

I got this error from serial monitor when add

#define RADIOLIB_DEBUG_PROTOCOL (1) // protocol information (e.g. LoRaWAN internal information)
// #define RADIOLIB_DEBUG_SPI          (1)   // verbose transcription of all SPI communication - produces large debug logs!
#define RADIOLIB_VERBOSE_ASSERT (1) // verbose assertions - will print out file and line number on failure
#define RADIOLIB_DEBUG_PORT Serial

and here is the all console:

To quote @HeadBoffin:
"The answer you seek arises well before any attempt is made to send a message, in fact, its on the very first line of the debug output! You can look it up in the TypeDef.h file!"
There's also some info on the Wiki IIRC. Probably something with the interrupt pin or power supply.

[ezefferth]

I tryed to enable debug from SPI and the end of looping shows RLB_SPI: CMDReset reason: 9.

I tryed radio.begin(915.0, 125.0, 10, 5, 0x12, 10, 8, 3.0, false);
I'm thinking the problem is in TCXO voltage, but, I put it in radio.begin, and always drop device in reboot.
I try many forms,

hmm, I tryed to config
SPIClass spi = SPI;
SPISettings spiSettings(2000000, MSBFIRST, SPI_MODE0);

and

SX1262 radio = new Module(41, 39, 42, 40, spi, spiSettings);

and the setup()

spi.begin()

I tryed spi.begin(41, 39, 42, 40); .. and nothing.

[ezefferth]

Also, i tryed to radio.XTAL = true; and the error:

[ezefferth]

my device model Wio sx1262 and xiao esp32s3 (seedstudio)

[ezefferth]

I tryed other lib and I have success into connecting OTAA. My gues, is something at config is making conflict, like voltage in TXCO, or dBm. When i radio.begin() how I test the config init after begin()?

[ezefferth]

The maxEirp = 30 dBm aways that. Is there something to push a error?
