Hello Forum,

in order flashing images I built esptool and mkspiffs as a standalone exe for Windows,
because I'd like to config my little app outside an esp-idf.
Both exe seem work fine, but with the exe stuff no data are read from the config.txt.

Making the spiffs image on Windows:

Code: Select all

mkspiffs.exe -d 5 -c image -b 4096 -p 256 -s 1048576 spiffs.bin
esptool.exe --chip esp32 --port COM3 --baud 115200 write_flash -z 0x110000 spiffs.bin

output

Code: Select all

D:\Source\esp\bitbucket\esp32-uartbridge\bin>mkspiffs -d 5 -c image -b 4096 -p 256 -s 1048576 spiffs.bin
Debug output enabled

D:\Source\esp\bitbucket\esp32-uartbridge\bin>esptool.exe --chip esp32 --port COM3 --baud 115200 write_flash -z 0x110000 spiffs.bin

Are there any hints where is the difference?

indeed there is a difference how the mkspiffs make the images.
So if I extract an image from one mkspiffs with the other one
a config.txt will be created, but the content is garbage.

Obvisouly there ist something happened while building the mkspiffs
with plain mingw32 outside the msys2 env. It seems not enough
install a plain mingw32 and run a make dist.

Do anybody know the right way compile a mkspiffs outside msys2?

Cry ....
this is coused by different kind of implementations.
Testing different stuff I use a directory which holds the extentions I cloned from the Internet,
from there I depoy them to the projects.
So I obvisouly did something wrong while cleaning up. SORRY

In the result I was working with two different versions/implemtations.
One Version of mkspiffs from https://github.com/loboris/ESP32_spiffs_example.git doesn't work at all in my case.
Neither msys2 nor plain mingw.

Regarding to loboris todays latest SPIFFS Example I may need edit include/sdkconfig.h
CONFIG_SPIFFS_META_LENGTH from 5 -> 4 and all works fine.

sdkconfig.h:

Code: Select all

#define CONFIG_SPIFFS_USE_MAGIC_LENGTH 1
#define CONFIG_SPIFFS_CACHE_WR 1
#define CONFIG_SPIFFS_CACHE 1
#define CONFIG_SPIFFS_USE_DIR 1
#define CONFIG_SPIFFS_META_LENGTH 4
#define CONFIG_SPIFFS_USE_MAGIC 1
#define CONFIG_SPIFFS_PAGE_CHECK 1
#define CONFIG_SPIFFS_USE_MTIME 1
#define CONFIG_SPIFFS_GC_MAX_RUNS 10
#define CONFIG_SPIFFS_MAX_PARTITIONS 3
#define CONFIG_SPIFFS_OBJ_NAME_LEN 32
#define CONFIG_SPIFFS_PAGE_SIZE 256

Hi.
I am using the Arduino development environment and would like to have the capability to write a program to go on to the ESP32.. and then at a later date enable the end user to load a new SPIFFS file system on to it.

I have bot the executables esptools.exe and the mkspiffs.exe (the correct win32 Arduino version)

My issue is that I am totally confused as to how to run them with all the parameters like starting memory etc.

Can anyone show me a working example so i can understand this or just use it.

many thanks
Dave
