I was able to re-flash the factory partition using the API
Thanks!

I configured my partition table with
- factory partition.
- one ota partition
(also using - custom bootloader)

The reason for not having two ota's is that my ota app is large and the 4MB flash can not hold ota0+ota1 (ota app ~ 2.1MB). Thus, created a factory app (~1MB) to re-flash the ota app ...

I came up with a compromise solution:


set(PROJECT_VER "4.0.1")
set(PROJECT_VERU ${PROJECT_VER})
set(PROJECT_PREF "myproject")

string (REPLACE "\." "_" PROJECT_VERU ${PROJECT_VERU})
set(PROJECT_BIN "${PROJECT_PREF}_${PROJECT_VERU}")

include($ENV{IDF_PATH}/tools/cmake/project.cmake)

project ...

It looks that this is a problem with cmake.
If i replace dots with underscore 1_0_1, it works.
.map & .elf files are produced correctly (with dots)

Any further suggestion?

Thanks.

Hi @chegewara,
this is smart approach.
Indeed, it will produce {projectname}_1.bin for (1.0.1) PROJECT_VER.

I tried to concat the two strings out side like

set(PROJECT_VER "3.0.1")
set(PROJECT_PREF "myproject")
set(PROJECT_BIN "${PROJECT_PREF}_${PROJECT_VER}")

project(${PROJECT_BIN})
but same ...

I managed to set app version number to project using PROJECT_VER in " CMakeLists.txt ".

If I compile the project, it will produce {projectname}.bin.
I can read the version using code. However, all versions have same bin name.

Is there a config variable i can use to make build produces distinctive ...

I changed to float per recommendation. Now both platforms produce same result.
Yes, I experienced slow processing so I opted to go to float.

Thanks for support.

Hi,
I have a code that uses "double precision" sin/cos/asin/acos/atan/fabs functions.
I get different results when running same code on PC and ESP32 (IDF 4.0).

Is there a compiler/config settings or external lib that I should use to get same results?

Thanks.
