Re: Filesystem size with custom STM32F7 build

Glad it worked!

Sorry I have been swamped and forgot about this thread. That last part is the part that has either changed, I forgot, or do not remember so I am glad it is noted here.

Re: Filesystem size with custom STM32F7 build

Understand,
I have been too busy to play with it on my own hardware to confirm my suggestions. I know it can work but not sure what I am missing. The crash is usually due to a continuity issue and writing where it should not.

Re: Filesystem size with custom STM32F7 build

Being busy often gets the best of me, but I would agree that the F767 should have an optimized 2MB version especially since it is on a mainstream dev board. Since I have not pursued this router because I ended up choosing an external flash, I think once the dev board is working as hoped and after so...

Re: Filesystem size with custom STM32F7 build

Yes, those corrections sound good. I have not tested these so yes please do not blindly trust me.

Re: Filesystem size with custom STM32F7 build

Might help with add some visualization to my last past. Finally realized that I can use code for pasting my tables correctly. | Sector | Size KB | From (Hex) | Too (Hex) | Original | Modified | | ------ | ------- | ---------- | --------- | -------- | -------- | | 0 | 32 | 08000000 | 08007FFF | 32 | ...

Re: Filesystem size with custom STM32F7 build

Sorry work deadlines are keeping me distracted. As Dave pointed out as well the sectors need to be continuous and cannot be broken up (using a segment can get around this a little) or you will cause issues, like you have seen. I went through this same thing when playing wit hit as well. Regarding th...

Re: Filesystem size with custom STM32F7 build

Sorry work got in the way of my "play" time and I should be able to work on this today. A key thing to know is that Micropython re-purposes the normal flash for firmware into a filesystem, that is why the flash is broken up. The filesystem needs to be managed by a buffer that can only be so big for ...

Re: Filesystem size with custom STM32F7 build

Can you confirm exactly which nucleo board and MCU part number? I can look into this more specifically for your MCU which might be a little different than the F767. ISR is the interrupt service routine TEXT if I remember correctly the filesystem The manual will have more details than the datasheet w...

Re: Filesystem size with custom STM32F7 build

Understood, I have and you definitely can extend flash. At first glance on the flash layout you should be able to get at least another 128k out of it. I have forgotten to push this in the past but to keep thing "generic" there was no special cases for the larger flash F767 devices so they are not as...

Re: Filesystem size with custom STM32F7 build

Hello, Understood about you wanting it internal. In the case cost was the issue, the external flash is cheap relative. The one I use is $0.56 for single units. https://www.digikey.com/product-detail/en/adesto-technologies/AT25SF161-SSHD-T/1265-1230-1-ND/6124886 The biggest problem I ran into is that...
