GSoC/2016
v67 v68 87 87 * June 15: This week I tried to run JTAG. And came to know that there is already some [https://asuolgsoc2014.wordpress.com/2015/07/14/jtag-code-loading-and-debugging/ problem] of JTAG with raspberry pi. So I was not able to use JTAG for debugging purpose. I should have done some more research before buying the JTAG. That could have saved a lot of my time. So, now the only option left for me to debug the problem is putting printf statements in all the code which I added. Using this approach I have narrowed down the problem till some extent. The program hangs in one of the ofw bus status call. While adding the code from freebsd I had to add many files due to compilation errors. Now my plan is to add all the file one by one, analyse all the errors causing it and debug. 88 88 * June 24: I have successfully ported the bcm283x_dwcotg driver for the Raspberry Pi. I ran init0 test on my Raspberry Pi Model 1/B+. Driver loaded successfully without hanging. Changes can be seen [https://github.com/deval-maker/rtems-libbsd/commit/fd650f7ded413a0d891b5395abb0c8768d71acc7 here]. Apart from that I am getting error in mailbox functions (failed to set power state, err=-2). As far as I know Pavel and Mudit are looking into this problem. I will start working with them for the same. I can not move to next part before solving this. Also, I gave the work done till now for code review. 89 * June 29: Mailbox Error resolved. bcm283x_dwcotg ported successfully.Currently I am trying to port usb_ethernet driver. Resolving errors while compiling. 90 * July 13: I have added files for usb_ethernet and bcm283x_dwcotg till now. I am stuck at the point where I have to connect both of them. I have started the [ https://lists.rtems.org/pipermail/devel/2016-July/015564.html email thread] regarding this issue. Alan and Chris are looking into the problem with me. 89 91 90 92 == Wonjun Hwang ==
