Rcving Error: "E (30) esp_image: image at 0x1000 has invalid magic byte E (31) boot: failed to load bootloader header!"

Downloaded latest board files into IDE 1.8.2 and receiving the following error messages:

This first mentioned in #334 . Tried different upload speeds and did not work.

To test whether the problem is with the ESP32 or the IDE I copied the previous version of the library that I was using into the 1.8.2 hardware folder and uploaded the Blink sketch. It worked fine no problems. Yes it blinks. Not sure what version I have, but the json file is dated 2/4/17 along with most of the files. The make file is dated 2/20 if that helps.

Thank you
Mike

[me-no-dev]

so you are not sure if you are running the latest code? Did you resolve this?

[mjs513]

The problem surfaced with the latest code. The old code dated 2/20 worked but the last version I downloaded didn't. I see you just did an update for the chip id. I will download as of today and give it another run.

UPDATE:
Just installed the latest updates and tried loading the blink. Uploaded fine but I still get the message:

i'll have in a few minutes a new update with new bootloader and all. Please give it a go once it's merged (5-10 minutes tops)

[mjs513]

Not a problem. Will try later today and let you know how it works.

[me-no-dev]

It's merged :) 376961d

[mjs513]

No luck. Still getting the same error. You want I zip the version that works?

[me-no-dev]

ok what board are you using exactly?

[mjs513]

Onehorse's ESP32 board.

[me-no-dev]

do you have that board selected in the menu? that one has specific issues with flashing ;)

[mjs513]

Yes I have that specific board selected in the menu. Had no problem when using the older version of the ESP32 Lib. Something seem to have changed between versions I am using. I first mentioned this in issue #334.

The first production batch of ESP32 boards was shipped yesterday so I will be able to send me-no-dev one next week or so. Maybe this would be easier than remote debugging. I haven't updated the ESP32 Arduino core (afraid to!) since the first time I got the board to work using Igrr's bootload.bin file. I am sure once me-no-dev has the board the problem will get sorted out in short order.

[mjs513]

Thanks @kriswiner . Just wanted to let you know the issue with the new core.

@me-no-dev and @kriswiner. As a hack I took the bootloader.bin file from the version that works and passed it in the one I just downloaded and it worked no problem. Didn't think about doing this until @kriswiner mentioned the bootload.bin file in your post. At least I have a workaround for the new core. Think @me-no-dev is going to like the board. I have to order another as backup now. Not sure what changed in the bootload.bin file.

[me-no-dev]

I'm waiting for the board :) will do my best once here!
