Embedded programming tutorials for i.MX35

Hello everyone,

I am a newbie in this whole embedded system world. I am trying to find any tutorial for c programming on i.mx35 pdk with linux 2.6.31 running on it. So I think it will be nice if we can start sharing some sample codes on this forum, I bet this will help a lot of people, especially new embedded programmers like me. Now I know there is Code sharing center in this forum but I just don't have any code to share yet.

As a start for example, what is the best way to access the registers on the i.mx35? For instance, if I want to access the SSI bus, I need to access its registers. How can I write a simple C code to do so? How can I start and what are the files I should include in my code? If anyone has any sample code to access any kind of registers , please I would really appreciate it if you can share at least some tips with me. I already searched the freescale forum but I couldn't find the help I need, but then I found this community forum so I thought that this is where I should first go for help.

Thank you in advance.

Hi Eric, In one of your tutorial videos, linux_training_part2F, you mentioned that we can take a look at your LCD code, but for some reason I can't access the website to get the code. If you don't mind, I was wondering if you can provide me with your code. Thank you so much.

If you goto www.EMGRobotics.com under the Linux tab, I have posted all the i.MX35 linux training I did last year. I have the training in video and powerpoint formats.

Thank you Eric for sharing your videos with me; it is very helpful as a start up tutorial for LTIB installation. Right now, I am trying to write a C code that I will compile and run on the i.MX35. I was able so far to do so except when it comes to dealing with memory and internal registers. Currently my codes don't deal with any memory or interrupts or anything. My main goal is to transfer data to the audio codec pins on the personality board. If I am not mistaken, I need to write the data on the SSI bus with I2S mode enabled. Where do you think I can find a sample C code that shows me how can I deal with internal registers and memory on i.MX35? Thank you so much for all the help. Sam
