Re: [microblaze-uclinux] Microblaze uClinux 2.6.11



Hi Mark,
 
having or not having uClinux 2.6.x support for MicroBlaze may easily mean extra 3 man-month development time. So when it comes to decision making for new projects then that that time may already already be significant factor. I feel that I maybe used to heavy words making this point, but I really think it is a necessity to have MB uClinux 2.6.x ASAP. There are pretty many drivers that are either just not there or not working properly or need more development time for 2.4 then for 2.6 - as example Philips has released the source code for the ISP176x USB host-device chips under open-source license. However the only version that is open-source is for linux 2.6, there are other examples as well where providing support for 2.4 is way more complicated then for 2.6 kernel. Open-Source USB host-device IP-Core (from opencores) - again it comes with linux driver, but only for uClinux 2.6.11 (for NIOS2! ). SDIO drivers are not available for 2.4 at all ASFAIK, etc. etc.
 
Sorry again if my postings about the 2.6 did use not so easy wording. But I really felt that the topic is of that importance that even knowing that something is coming may save time for many of us (by not having to deal with 2.4 anymore). So I hope that the MB uclinux 2.6 support is really really happening in some foreseeable future.

From an official perspective??

 

My job at Xilinx is to provide our customers with the 3rd party SW and IP support that they need for their product integration of Xilinx?s technology. To this end I have to consider not just the OS porting itself but tools and support as well looking towards the user?s experience with the whole product.

 

We (Xilinx) are engaged with PetaLogix who we regard as a Tier 1 partner for our Embedded Ecosystem. They are a real company with real product, however young they may be, and Xilinx will continue to support them in their growth going forward.

 

Because the popularity of uCLinux and the amount of associated work (and open source Linux as well) continues to grow, Xilinx has also engaged with a mature Linux company for uCLinux and open source Linux porting, support and tools. Because of my position at Xilinx, I can not say who this is until the official press release. This is not to say that we no longer have a relationship with PetaLogix ? quite the contrary. PetaLogix will be involved in these efforts. Five months ago John and I tried to build a 3 way partnership with a company that would provide support and a commercial tool chain to complement his OS product. This relationship would have provided uCLinux developers a world class product followed by world class support and world class tools. Unfortunately, this deal fell through and it has taken until now to close with another partner.

 

So, all this being said, it is not John?s issue that there is not yet 2.6.11 support. If you need to question Xilinx?s uCLinux 2.6.11 support then question me because it was my decision not to fund PetaLogix directly for the uCLinux 2.6.11 port.

 

Best Regards,

Mark Jensen
