| OpenSSL FIPS Object Module FIPS 140-2 validation now includes ARM Processors |
|
 |
|
console server writes "Opengear in partnership with OSSI and the OpenSSL project has delivered an extension of the existing OpenSSL FIPS Object Module v1.2 validation (certificate #1051) that enables that open source cryptographic module to meet the FIPS 140-2 standards for ARM processors.
The OpenSSL certification has previously only covered x86 based systems. The extension delivered as part of OpenGears involvement now allows for
ARM based systems to fall under the certification. It also paves the way for other embedded/cross compiled systems to easily follow.
OpenGears IM/CM/SD4000 and CMx86 solutions are all built upon the
open source uClinux and okvm console management software."

| Size Reqirements for uCLinux |
|
|
|
|
cplusruss writes "We are doing some very preliminary die size estimates for a custom IC we're looking to design and build. The IC will use an ARM7 core, and we'd like to run an embedded version of uClinux. The main reason for using uClinux is to support TCP/IP and ZigBee protocols.
Have you any idea of how much code space (ROM and/or Flash) and RAM we will need for this basic configuration (excluding the rest of our application software) ?
Thanks
Russell"

| New uClinux port in works to new Free core |

AnthonyGreen writes "I'm in the process of designing a free software core called moxie along with the requisite tools and firmware suitable for implementing in FPGA technology.
The tools ports are already in the upstream GNU repositories, qemu is ported, and uClinux is just starting to boot.
Click here to read the development blog. There's also a wiki here. I am new to uClinux, so advice and help is certainly welcome!"

I'm using a board with CPU S3C2510, whose core is arm940t. The cross compliler is arm-elf-gcc 2.95.3. I choose the uclibc in the menuconfig. My uclinux is 2.4, which is provided by samsung and is called linux2510.
Does anyone know this question?

Stephan Moser writes "The leanxcam is an Analog Devices DSP smart camera (ADSB-BF537) aimed at industrial computer vision applications and hobby/student projects. The entire camera - hardware as well as software - is open source.
It features a 752x480 pixel CMOS sensor, 64MB of SDRAM and 4MB of flash, Ethernet and div. IOs.
The camera runs a uClinux and comes with an image processing framework. Further details are available under http://www.scs-vision.ch/en/leanxcam/index.html or www.leanxcam.ch.
The camera won the 2008 Vision Award."

Thanks for taking the time to complete the survey.
Results will be shared when (a) we get enough people responding or (b) a few weeks goes by."

| vfork with child and parent commication? |
|
|
|
|
Frank writes "Hi ,
I tried to replace fork with vfork inside a program. I found the program is hung in child process . the "read()" inside (send_receive function call)child process is blocking the program.
I am kind of new to uClinux or linux. please correct me if I stated something wrong.
I guess the reason:
- vfork is always to start a child process
- we can't execute parent process until child process has done.
- read() inside the child process is blocking call and waiting for parent but parent is waiting child to exit. there is a deadlock???
my question is :
How to resolve this problem?
regards
Frank"
