RFM69 library and Watchdog reset

[Rrobinet]

Hi,
I am porting a gateway application currently running on Arduino (and WeMos D1 mini) and using a RFM69 SPI transceiver to a WeMos Lolin32.
This one is connected using the SPI pins (SS, MOSI, MISo, SCK) and is using A16 as Interrupt.
It looks working find, however I have random SPI_FAST_FLASH_BOOT during data exchange (on heavy traffic once per minute 1 of 3 times and then back to normal) .
I spend already few days to insert yield() commands in several while loops and critical data transfer functions without success.
I wonder if somebody could help or to give me hints to investigate this issue.
Thanks
Robert

I'm getting similar error: https://esp32.com/viewtopic.php?f=19&t=3019. But it works fine when I use older version of esp32 arduino library.

Hi, @harishjp

Could you please indicate me where I may find this older version of esp32 arduino library.

Issue is related to the SPI transaction handling.
A modified version for test library for ESP32 is available on:
