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...

Hello All, My current project is to interface the display to the controller that gets the data through a Ethernet port and displays it on P10 LED display. I have a 16X32 P10 LED display. I have to make a 32X64 display with four such displays. The controller gets the data from either Zigbee or Ethernet (Using HTTP or TCP/IP protocol), extracts the information from the received packets and f...
