Has anyone had any issues with setting up ESP32 devices? After I flash and restart I see 

```````````````````````

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
mode:DIO, clock div:1
load:0x3fff0018,len:4
load:0x3fff001c,len:1100
load:0x40078000,len:10088
load:0x40080400,len:6380
entry 0x400806a4

```````````````````````

Then after I send %0&15; I see 

````````````````````````

I can't seem to get it into the configure mode to set up the wifi connection. I did flash using esptool directly as I can't seem to get USB to pass through to the VM that run windows. I copied the command from the install tool so I think its correct. 

`esptool.py --chip esp32 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0xe000 boot_app0.bin 0x1000 bootloader_qio_80m.bin 0x10000 BruControl.45B.ESP32.W.bin 0x8000 BruControl45.ino.partitions.bin`

Looks like the firmware is loading correctly but the setup data isn’t storing properly. We’ll have to test it and get back to you. Will be a few days before we can.

I was trying to flash another esp8266 and I couldn't get that to work either. I managed to find an old Windows on a stick device and using that I was able to flash and setup both the esp8266.

So it looks like the issue was how I was flashing from a Mac

Are you saying the ESP32 is working too, or just the 8266?

yes I got both ESP32 and ESP8266 working by using a Windows machine to flash them.
