uCLinux on STM32F429I-DISCO

Hi everybody,

I was very happy to see uCLinux port for Cortex-M4 and my favorite MCU STM32. This well done job was achieved by emcraft. So I wonder that is it possible to run uCLinux on my new toy STM32F429I-DISCO? I have started for it and some u-boot and kernel patching I finished my first job. You must known that code execution from SDRAM on STM32F4 much slower than from FLASH (~6x times slower). So in fact this core is not suitable code execution from SDRAM. But maybe you don't have any chance so you can accept this penalty. Than I modified the kernel to load romfs from flash, simple frame buffer driver, u-boot patching for SDRAM and LCD init functions. You can try and decide for yourself. This is boot-up and simple framebuffer demo video.

Emcraft original source git is https://github.com/EmcraftSystems (not including STM32F429I-DISCO board drivers)Sample image attached to the post. This image contains u-boot, kernel and romfs. The serial console is USART3 and PC10->MCU TX, PC11->MCU RX. Don't forget that this interface has TTL levels. #usart #stm32-uclinux-u-boot #usb-driver-p19-stm324f

Hi. I'm totally newbe for uClinux and for STM platform. Is possible to write more information about uClinux here.. what all command is possible to use , and if support any USB mass storage or SD card ?? and how to write easy small program (for example hellow world ) in Windows PC ??  best regards..

This seems a bit remedial for this thread, suggest you start a new one if you are looking for tutorials and basic stuff. I'd also suspect you could find a lot of this type of stuff with a Google/Bing search.

Ehm.. yes. but if try searching in google .. stm32f429 + linux show only this web forum.. hehe.. I ned only small help ..

ok .. thanks for all .. best regards.

Hi.Today I try install and compile files for uClinux.

I use scripts from gore.mike but had problem to do it.. after install or compile say error.. What I do : 1. To my WIn7 64-bit install Oracle VM and to this VM install Ubuntu 12.04 LTS 64-bit version 2. in home directory create new directory with name uCLinux 3. download all scripts from gore.mike and unzip to my uCLinux directory 4. open terminal and start run step by step run scripts 5. ./setvars

root privileges required

Did you notice this line ? When installing Linux, either for ''real'' or in a VM box, you define a root password. Try using it here.

Hi. 

I try run all scripts but still have some problem.. then :Is possible some one to run all scripts in PC and record all output in terminal to file .. and send to me ?? then I can compare with our output .. and more easy to solve problem.. is possible to do it ?? best regards.

Hi tmk,

Can we use usb wifi on stm32f429-discovery? It is working on LPC1788 under uClinux Best regards, THANH NHI

Hi,

the kernel doesn't contain USB HCI drivers for STM32 rightnow. I couldn't find any time to add this driver :(

Hi. Then try use driver for  SD card only .. if you have driver.. I know .. in dev kit is not sd card slot .. but this is easy to add this by wire to connect.. and make uClinux distribution with SD card support .. external drive ..and make some small program to run from SD card (mount automatic if GPIO pin is toggle to GND) ..  and is possible to create file in internal FLASH ?? copy file form external SD card to internal flash.. this will possible to run program with no SD card inserted.. and start automatic..  

best regards
