Chronicles from our peeps.
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…
For the most part of this week I was exploring new ideas, exploring Wt’s capabilities, debugging some annoying bugs, and designing algorithms for some objectives. First, let me start with the interface bug. Slow connection rendering bug When the interface was changed to the current one, a weird bug occurred Read more…
Last week, I am still doing on contiki’s functions testing in my new porting microprocessor and platform. After 1 week plus of function testing, the basic functions are working in my porting microprocessor and platform. The process in contiki OS called protothread. All of those protothread are scheduled in cooperative manner. Read more…
This week my job scope was about the TCPIP. I need to use the PICDEM.net 2 as a TCP echo server that listen on a TCP/IP socket and transmits back exactly everything that it receives. There are some demos in the microchip application library, what I have to do was Read more…
For five weeks in row we have been working on the enhancement of the code. I really don’t know why it’s taking that much time. Is that what usually happens in any project developing?! Feel like we are in infinite loop… Hopefully we will reach the “break;” statement soon. Lol Read more…
This week, I finally get the RISC-V Angel Simulator to run the C/C++ code compiled from the default RISC-V GNU compiler, which is specifically designed to compile files into ELF file that to be used with the RISC-V Spike and Proxy Kernel. I had verified that the bootloader extracted from Read more…
This week I gained a deeper and clearer understanding about some terminologies and the flow within a compiler that I have posted last week. Frontend Basically it uses a parser to produce the syntax tree abstraction of a given source file. It will translate source codes into intermediate representation (IR) like Read more…
This week, I had really a hard time with RISC-V Angel. It started with finding the bootloader code from the RISC-V Proxy Kernel, as the bootloader is the primary program/codes that needs to be load up before the main program actually runs. I searched all over the proxy kernel code and Read more…
My task of this week is the configuration of FPGA. I had to configure the Spartan 6 XC6SLX9 FPGA in the slave serial mode, by using the USART port in the PIC18F97J60. This is something really new to me and web references are scare. Therefore, the only way is to Read more…
