Erase?

[beicnet]

Using latest bin: esptool-0.4.11-win32.zip

But how I see, I can't erase my WeMos D1 mini

esptool.exe -cp COM7 -cb 115200 -cd nodemcu -ce
warning: espcomm_send_command: didn't receive command response
error: espcomm_erase_flash: FLASH_DOWNLOAD_BEGIN failed
error: Invalid argument or value after -ce (argument #8)

btw...but I can flash it without any issue.

I believe you can’t flash it too, based on the log you send

@nissimzur Yes, I can, I flashed it a few times yesterday and today too, but can't erase, I thinks its related to timing.

Just send a bin file that has 0xFFFF all over. www.telnt.com From: beic [mailto:notifications@github.com] Sent: Tuesday, July 18, 2017 12:19 PM To: igrr/esptool-ck Cc: Dr. Nissim Zur; Mention Subject: Re: [igrr/esptool-ck] Erase?

I also found out that I can't erase but "flashing" is working of sorts.
The flash is accepted but the ESP doesn't seem to reboot into running mode. Will do further tests.
What I did find I was able to flash a general sketch to a "dead" ESP01 and then return to the Arduino IDE and now it's running with an OTA hostname of Lazarus. I have a few dead ESP07's and at least one dead WeMos so I will try to resurrect them too when I have time.

I figured out, that it will erase, but also will freeze the command prompt window for a while, is it a bug?

[pieman64]

Tried again today and erasing flash still doesn't work. Argument #8 error as per @beicnet
Anyone have a real fix?

[beicnet]

@pieman64 Unfortunately, there is no explanation given for that issue yet.

[nissimzur]

The chip does not "know" if it flashes a bin file filled of 0xFFFF or a code.
So, if you can flash 0XFFFF ok or other data, it must flash good apps bin file.
If it does not run, you have a bug in your bin.
Call my SKype nissmi.test I will help

@nissimzur We are talking here about "erasing" chip with command line prompt
