Sounds like you need to become more familiar with the software you have chosen first as part of the due diligence process. You should perhaps see if Emcraft provides consulting services, or can point to some providers, as there isn't much traffic related to ucLinux on this forum.

Suggest you review the Emcraft FAQ, which specifically covers FLASH/RAM requirements.

You can no doubt augment that knowledge by trying some builds including the tools/application mix(es) you expect to need, or want to support.

I successfully booted the kernel on the STMF417 with only the internal SRAM and FLASH.

The kernel was about 500K and was running directly from the flash memory.At the end of the boot, I had left 32KB of RAM for applications.I know it's useless, but may work for someone who would want to exercise kernel development with the cheapest ever STM32F4-Discovery board.

Luiz, thank you for the information. What kind of features and applications did that provide? Presuming that was mainly the kernel, and the rest of the space could be used by an application.

I'm expecting to see a 2MB F4 shortly which should provide additional resources.

can you provide a patch.

I'm still trying to build a small initramfs with a tiny build of busybox. After that I have to turn the initramfs into initromfs because there is no space in ram to aford a fs. I expect to release the patch in the next couple of days.

The main problem I'm facing now is that the kernel is recognizing the bFLT busybox executable as a bin_script. Any ideas to help on that? BR,Luiz Renault

Can you share the boot log to try to understand the problem, maybe enabling the debug in the binfmt_flat loader may help.

I can help to debug if you send me a binary image of the kernel I can run on my discovery and the System.map file. which kernel version & busybox version are you using? BR

I believe the problem is with Busybox. I made a custom init program with simple shell and it worked.

All the links are dead and I'm searching for the uClinux distribution for the STM3220G-Eval board.

Any suggestions where to find it? Thanks in advance

Hi Pandey,

uCLinux software solution is provided for free by ''Emcraft Systems'' company. You can get more details

. I have also 2 comments: 1- This is a very old thread started on 2009. It should be better to start a new discussion for new requests even if the topic is the same. 2- It is not possible to get access to personal mails in order to send packages. -Mayla-
