Introduce the issue

I've just received this information from TL Lim from PineStore : the current SPI flash memory chip (XTX XT25F32B) is EoL (end of life) and will be replaced by another one : BY25Q32ESWIG.

Here is the datasheet : BY25Q32ESWIG-03.A.02.00372.pdf

The only change expected on the software point of view are the JEDEC IDs :

PineStore asked me to provide them with a new firmeware that supports this new chip.

Feel free to forward this announcement to all firmware developers that might be interested to support this new flash chip!

Preferred solution

At first sight, no change should be necessary in InfiniTime, since it does not check the IDs (it only logs the value, but does not fail if they are not the ones that were expected).

However, the SPI flash driver in the bootloader will most probably fail since those IDs are specified and checked at boot time.

Since the bootloader is a very critical part of the project, please feel free to cross-check my analysis and also test and provide feedback when a new version of the bootloader will be available :)
