Same here. I need to implement J1708. No issues at all with the ESP8266, but the new driver seems to be a bit of a mess.

And PLEASE, if you are connecting to a vehicle, use a proper automotive transceiver instead of the MCP2551 piece of junk. TJA1042TK/3 would work fine and has the correct logic levels for the ESP32.

A note - unless you are only going to configure on a hard power-up (instead of after firmware OTA or other reset), you should add the following after the Pelican mode change [MODULE_CAN->CDR.B.CAN_M = 0x1;]:

MODULE_CAN->MOD.B.RM = 1;

Otherwise, the code cannot change the module configuration.

Good to know, thanks!

In case anyone is following along, looks like this is the operative paragraph: App partitions have to be at offsets aligned to 0x10000 (64K). If you leave the offset field blank, the tool will automatically align the partition. If you specify an unaligned offset for an app partition, the tool will r...

It would be amazing to get some sort of response here........... When I adjust the flash tool to flash both regions and then manually switch, I get the following: I (118603) setupgrade: OTA Partition: 3FFB9A68 E (118662) esp_image: Segment 1 has load address 0x3f400010, conflict with segment data at...

Also, here is my partition table [2MB flash]:

# Name, Type, SubType, Offset, Size
nvs, data, nvs, 0x9000, 0x4000
otadata, data, ota, 0xd000, 0x2000
phy_init, data, phy, 0xf000, 0x1000
factory, app, factory, 0x10000, 0xF8000
ota_0, app, ota_0, 0x108000, 0xF8000

Just in case I wasn't reproducing the binary correctly, I tried to write the OTA section with the flash tool as well: python /c/ESP32/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port /COM4 --baud 2000000 --before default_reset --after hard_reset write_flash -z --flash_mode dio --...

If I change the partition table to rename the OTA partition to #0, the above step succeeds, but it doesn't boot correctly: I (12) boot: ESP-IDF v2.0-rc1-725-g07b61d54-dirty 2nd stage bootloader I (12) boot: compile time 22:59:14 I (13) boot: Enabling RNG early entropy source...
