Im interested in this too...all of the existing MCP2515 drivers rely on Arduino bits and just dont seem to work with ESP-IDF that well.
I havent been able to find one that really works nicely/natively with IDF.

ESP32-WROOM-32E
I assume the new ESP32-WROOM-32E is just the newest revision/replacement for the ESP32-WROOM-32D?
The ESP32-WROOM32E is a direct replacement for the ESP32-WROOM32D, no changes needed?
Nice to see the lower price of the ESP32-WROOM-32E!

Re: What would you like to see in The Next Chip?
Wrt multiple CAN buses and CAN-FD: We heard you on the 'multiple CAN buses' front, I don't have any specsheets in front of me but I'm pretty sure we're going to have some chips with multiple CAN peripherals. We're not planning on supporting CAN-FD at this moment. This is great news that future chip...

Re: Migrated to ESP-IDF, now CPU won't start
Might be an incompatible bootloader. There are some arduino bootloaders that are incompatible with ESP-IDF.

Re: CAN OTA USED TOGETHER WITH ESPNOW
There is some bug/issue with using the CAN driver and OTA together...im not sure exactly what the fix was, something to do with running the CAN driver from IRAM.
edit: oh wait, did you mean "can OTA be used together" or CAN bus and OTA together...?

Thanks for reporting, the fix on master is available on https://github.com/espressif/esp-idf/co ... 7f735b9fef

Thank you for looking into this.
Does this fix work on IDF-3.3?

Re: CAN vs OTA: interrupt watchdog timeouts despite delay in OTA and IRAM_ATTR in CAN
So far, this is working well with code in IRAM, with 300ms interrupt watchdog timeout it is not being triggered. The loss of IRAM was <2KB, whereas just moving mbed_tls buffers to IRAM recovered about 40KB. I have not yet reverted the OTA delay and tested with a large partition, will be interesting...

Re: Get SHA256 of SPIFFS partition?
Hi dmaxben, Yes, this will be it. There is a limit to the total amount of flash which can be mapped at one time in the address space. This is a bug, we'll fix it (the routine should map the region in chunks to handle this). Not certain if this fix will be backported to v3.3, though. Angus Ah ok. Is...
