Although this was not my final week (my next week is), yet this is my final blog. As next week we will be working on something different (writing tutorials), I wanted this blog to be my goodbye letter. 29 weeks are over, during which, I learned a lot, I worked a lot, I’ve got scolded A LOT, and, although now I regret it, I got into disputes with my “mentor” a lot. I am really sad that it is over Read more
Last week, I found that the value pxCurrentTCB is different from the instruction address of my task created. After discuss with Dr Shawn, he told me that the value of pxCurrentTCB should be different from the instruction address of task created inside elf file. The pxCurrentTCB is holding the stack address of a task. So I found my concept is wrong and pxCurrentTCB is holding the correct stack address. When the task created by calling function xTaskCreate, a TCB will be Read more
With minimum expectation and completely blind faith I had arrived at AESTE for the beginning of my internship of 12 weeks. Just to give a background, before I proceed with my blog, I am a Bangladeshi student studying Electrical and Electronic Engineering in Malaysia and I have been here for 3 years now. It was important to mention as it is very rare for people to encounter Bangladeshi, that too a girl, studying Engineering in Malaysia. Getting back to my Read more
As my colleague started to modify the linker script, I found more problems to be solved in the simulator. The RISC-V Angel Memory One of my concern this week is to set or limit the memory that could be created by the simulator, which is also the size for the RAM of simulator. The default RISC-V Angel RAM is set to 8 MiB (MegaByte), which can be calculated from Total Memory (byte) = 1 x 1024 x 1024 = 10485760 Read more
I still can’t buy the fact that this is my last time to write an official blog as AESTE intern. Yes! If you haven’t figured it out yet… I’m the type of person who hates all the goodbye thing. 🙁 I do still remember my first blog I wrote, my first days at AESTE and how nervous I was. All these memories seem like just yesterday. Time really went by so fast, almost twenty eight weeks I spent here in Read more
Well this week I continued working on the project. Some bugs were solved, some minor modification for the code here and there and some modules and classes were added. The first issue I was working on was regarding the CodeMirror editor interface. The tabs of the editor weren’t in line. Some need a single tab and other needs double tabs to be in the same depth. The solution for this bug was straight-forward. The C++ mode that we use for Read more
Again, we spent this week fixing bugs and adding more components. We are not adding new features but rather working on the features that are already implemented. Here’s the summary of what happened throughout the week. More components We added more components to the web application. These components are LCD, Mtwi, Mspi. Previously we have had these components (Mtwi and Mspi), however we needed to change their names to Stwi and Sspi (hence, changing them from masters to slaves). So, Read more
This week I continued to look into tree dump files in the effort to find out the data passed to the plugin event. Honestly as I have posted before, information on analysing dump files are really hard to find online. Most of the information available are about the basic information about dump files but not how to analyse them. After searching for quite some time online, I have found only one resource so far from GCC Resource Centre, IIT Bombay that Read more
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 stack during creating task into the system. Once the task is needed to be run, the stack pointer will restore to the particular stack address. And the minimal task space 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 return response program can be performed. This was tested by using the telnet to send the commands, for example OPTION / HTTP/1.1. After finishing the simple receive and response task, Read more
