Re: Ip Connectivity Windows 10 unstable

I see similar behavior on Windows 10 using my MacBook Pro built-in WiFi (bootcamp mode). No issues with external USB adapter I picked up from Adafruit.

Re: RS-485 support

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.

Re: can bus circuit

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.

Re: About the CAN controller.

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.

Re: OTA issue

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...

Re: OTA issue

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...

Re: OTA issue

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 --...

Re: OTA issue

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...
