I success connected ESP-WROOM-32 via mpfshell, Micropython is "ESP32_LoBo_v3.1.18 - 2017-02-07" prebuilt firmware,
and success list ESP-32 file via "ls" command.
In /flash directory, I try to use "put xxx.xxx" to upload local machine file to ESP-32, but appear "Failed to create file: xxx.xxx", and use "get boot.py" to download boot.py to local machine from ESP-32, appear "Failed to read file: boot.py".
In /flash directory, use "md test" to create "test" directory and change to /flash/test directory, these operation ("put" and "get" file) above are success.
And other way, in Micropython shell, use this method like below is also success:
>>> f = open('/flash/boot.py')
>>> f.read()
This prebuilt firmware used SPIFFS with internal filesystem, is it mpfshell must required FAT filesystem? or /flash directory has some access permissions ?

I've tried with the same prebuilt firmware and it works fine.

Re: Can't modify content in /flash directory via mpfshell on LoBo port.
Hi folks,
I've run into the same issue but it seems a problem only on Windows.
I'm using ESP32_LoBo_v3.2.24 - 2018-09-06 on an M5Stack Core (no PSRAM) with mpfshell 0.8.1. Using mpfshell to connect to this from a Linux host (Ubuntu 16.04) works fine; files can be transferred. Using the same version of mpfshell on Windows prevents files from being transferred in either direction:
I've used Dave Hyland's rshell and, after working around an issue running rshell on Windows, it connects and transfers files fine.
I would be inclined to say this is an mpfshell issue however there appears to be no problems with mainline MicroPython on Windows:
In any case, we can use rshell as a work-around for now but it does seem that the Lobo fork is doing something different to mainline MicroPython and perhaps this is causing issues with mpfshell?
Boris, should I raise this as an issue on your issue tracker? Could it be a problem on the Lobo fork?

Yes as a windows user I also have problem with windows security blocking
Re: Can't modify content in /flash directory via mpfshell on LoBo port.
I don't think this particular issue is due to security blocking - for two reasons. 1) I tried running the console as Administrator and 2) mainline MicroPython works fine.OutoftheBOTS_ wrote: ↑Fri Oct 19, 2018 4:30 amYes as a windows user I also have problem with windows security blocking

Re: Can't modify content in /flash directory via mpfshell on LoBo port.
I am having the exact same issue on Windows but with an nRF52 and Micropython.
Somehow the initial upload if the file does not yet exist works but not if I try to upload it again. If I remove the file using mpfshell and try to upload again, I receive the error message "Failed to create file:" but it got uploaded.
Because I am using a script to upload multiple files and also create folders I added a command delete all files first and then upload them which seems to work, I do not receive the error anymore.
