EEPROM Reset issue

[mayurharge]

Hello,
I am using EMBEDIS library for handling EEPROM related functions.
I am getting the proper response for the first startup. but I am not able to retain the values after a restart.
the code works fine with [http://dan.drown.org/stm32duino/package_STM32duino_index.json]
board files.
Thanks

I guess you used the Bluepill? could you be more precise ? Sketch? build option...

[mayurharge]

Yes i have used controller from bluepill. stm32f103c series 128kb version.
Build options were default Just changed the upload method to serial and controller size to 128 kb.

Here is the link for sketch

https://github.com/thingSoC/embedis/blob/master/examples/Uno/Embedis_Uno/Embedis_Uno.ino

Here is the exact build config
Board "stm32f103c series"
board part no "Bluepill F103c8"
Seril interface "Enabled with generic serial"
optimize "Smallest(-Os default)"
Cruntime Library "Newlib Nano(default)"
flash memory size: "128K"

I will not be able to test before next week. Anyway, last time I've tested the eeprom emulation on F1 it was functionnal. I saw some core define usage in the lib maybe there is a small update to do also in the lib.
Did you test default eeprom example which do not use the lib? (Put and get example)

Okay i wil test that. Thanks & Regards, Mayur Harge

Hi @mayurharge
I've been able to test and reproduce.
In fact value are not reset and well present in the FLASH after a reset. (I've dump the flash)
Issue come from a wrong E2END definition. As EMBEDIS store since the end of the EEPROM it miss one data as E2END was defined as the SIZE instead of the last valid address.
Now it is working with #400

Thanks.
