For benchmarking C implementations, the there are a few benchmarks, but they all have their problems. Many benchmarks have memory requirements that are far too high or need functionality not necessarily available. Some are quite one-sided in what they measure (e.g. Whetstone, Dhrystone, Coremark). So, I deciced to write a new benchmark, stdcbench. I wanted it to be suitable for small syste...

Hi folks- Does anybody have any recommendations for static source code analysis tools based on practical use? My customer is asking us to apply a static source code analysis tool to an existing medical product. The product is undergoing changes for which the FDA requires another round of testing. The customer was dinged by the FDA for not using an analysis tool so they want to corr...

Use reserved vectors in Cortex-M3 vector table

Here[1] you will find the vector table of Cortex-M3 core. There are 4 vectors (16 bytes) that are named "Reserved" (plus one more at index 13). Do you think they can be used for custom purposes? The word "Reserved" seems this can't be done. I'd like to use those vectors, that are in the non-volatile Flash memory, to store some data. In my case, I will save the MAC address (6 bytes...

I'm using lwip that runs httpd over LPC1769 MCU. Now the filesystem for httpd can't fit the internal Flash memory anymore. So I'm going to use an external SPI Flash memory. I need some suggestions about a filesystem to use. I need: - a tool that creates a binary (or Intel HEX) image from a folder on my Windows development machine (the image will be downloaded to Flash); - file ma...

Hi, I'm developing a system based on Xilinx MPSoC chip, where multiple functionalities are controlled by AXI GPIO blocks. All those GPIO pins are accessible via sysfs interface. However, it is difficult to find the gpio chip and pin numbers from running Linux system. In the HDL design, the GPIO blocks are described by their names, but unfortunately those names are not propagated to

Hi, i have to port some code, which works on the RCM5750, to the RCM 6750. At the beginning I had some trouble with larger Arrays. Got the error message "Out of variable data space", fixed it by using the far qualifier for a large array and resizing the rootspace from 0x04 to 0x06. I changed the size with changing the define ROOT_SIZE_4K=0x06. After that, I'm able to run the code without gett...
