Chronicles from our peeps.
This week I am trying to implement the stack initialization to the system. Other than that, the FreeRTOS required programmer to make functions to save and restore context of the system during tasks switching. Every tasks in FreeRTOS required to save into the stack. The task is assigned to the Read more
My task was to include all the request method to allow users to interface with the web server. Inside the demo code of microchip TCPIP, there was a flow of state machine to receive and response the request. By modifying and inserting the request method, a simple receive request and Read more
Completion of Timer Interrupt This week, I had been working around with the timer interrupt, confirmed that the timer interrupt mechanism is actually correct after storing and restoring the 32 general registers that had been discussed previously. RISC-V control status register ISA only works around with the registers, but not Read more
Data Flow Analysis This week I continued in my search for reference in dump files analysis. In the beginning, I found something about Data Flow Analysis and when I look inside the content, it looks like exactly like Mathematics, probability all over again. There are a lot of symbols and Read more
This week I continue the work on the TCPIP. There are a many features in the TCPIP microchip allpication library demo, which are unnecessary. I had to remove these unnecessary features. Since many of these features were linked with each others, therefore I need to delete them one by one Read more
This week I trying to port another RTOS to our microprocessor. The purpose to learn this OS because it usually run preemptive operation in event scheduler. Same as Contiki, FreeRTOS also a RTOS design for small and memory constraint processor. Currently, FreeRTOS had successfully ported to plenty of microprocessor which consist products of Altera, Read more
One issue that I worked on this week was to change the objectList file format. The objectList file contains the list of the object the user has defined. Previously, we used a very simple file structure for the objectList file. Basically, evey component was written in one line and we Read more
This week a new millstone for the project release has been created. So we were working on closing our outstanding issues and completing the rest of the left features. Changing the Object-List File Format: Have you experienced the feeling that usually comes to a little kid who likes playing by Read more
This week, I worked on the implementation of Timer Interrupt using the RISC-V Angel. The RISC-V Angel had a timer interrupt code for itself for the usage of Linux ELF file. However, it does not state obviously how do they use it and why are they writing their code in Read more
This week I continued in my attempt to analyse the dump files produced last week. I happened to read online that the dump files are written in pseudo-C syntax, although pseudocode is supposed to be understood more easily, however it still does not make much sense to me. The dump Read more
