Re: Filesystem size with custom STM32F7 build

Sorry for no response. The baby has happened to our family so totaly not into micropython right now :D

The last sugested values didn't work for me. It shows increased storage space but crashes on data write. Will try more some day later.

Re: Filesystem size with custom STM32F7 build

Thanks for your help!

Double checking few numbers:

Code: Select all

{ 0x08040000, 0x20000, 7 },  <--- shouldn't it be here 0x40000 as sector size is 256k? 
and

Code: Select all

#define FLASH_SECTOR_SIZE_MAX (0x08000) <--- maybe 0x20000 for 128k?

Re: Filesystem size with custom STM32F7 build

Is it possible to reserve 256k of ram? How?
Will it be enough to run Micropython with remaining ram?

Re: Filesystem size with custom STM32F7 build

I was able to extend flash partition to 1.1 MB but MCU crashes after some data is written to it. l can write about 220 KB and after that MCU crashes. I guess it's an address issue and data gets written somewhere in a wrong location. Here's what I did: Added line to stm32f767.ld FLASH_FS2 (r) : ORIGI...

Re: Filesystem size with custom STM32F7 build

Here is my board https://www.st.com/en/evaluation-tools/nucleo-f767zi.html It has a STM32F767ZI mcu. MCU datasheet didn't had much about flash but I found this doc https://www.st.com/resource/en/application_note/dm00266999-stm32f7-series-flash-memory-dual-bank-mode-stmicroelectronics.pdf As my F767 ...

Re: Filesystem size with custom STM32F7 build

Thanks for an answer Travis! I have found similar information in https://forum.micropython.org/viewtopic.php?f=3&t=3702&p=22627&p22627#p22612 I have tried it but without any luck. I have no clue what those values are in flash.c file. First element (f.e. 0x08000000) should be address, second could be...

Re: Filesystem size with custom STM32F7 build

I am using Nucleo dev board so no options to add external flash.
Later i will be building my own pcb so i'll think about external flash.

Travis, do i get i right that you moved to external flash and didn't find a way to resize internal flash filesystem?

Re: Filesystem size with custom STM32F7 build

I would like to stick with internal flash for now but i need 200-300 kb of it.
Let me know if you will find something usefull.

Re: Filesystem size with custom STM32F7 build

Travis did you succeed with increasing filesystem size? Could you please share your changes? I have been working on updating the filesystem flash size based on the nucleo STM32F767 build. I get it to recognize (show is free using an os) a larger filesystem, but unlike my efforts with the STM32F405 e...
