Running software without an underlying OS (Linux, Windows, Android, ...)

[jimpanse]

Hey folks,

i want to run some code directly (without an OS) on my i.MX53 QSB. Can you help me with that?

Is there any documentation available?

Thanks!!

Hi Jimpanse,

You can run standalone code through JTAG. Chapter 9 of the users guide says how to do it. You can find the users guide in the following link:

About the code, you can write it in Eclipse, which is a freeware you can download from www.eclipse.org. After you finish the code, you can also compile it as a binary and flash it, this way you don't need JTAG.

Best regards.

Jorge.

Hey Jorge,

can you explain these steps a bit more detailed?

About the code, you can write it in Eclipse, which is a freeware you can download from www.eclipse.org. After you finish the code, you can also compile it as a binary and flash it, this way you don't need JTAG.

Which toolchain can I use? The CodeSourcery Lite Toolchain?

What do you mean by flashing without JTAG? Flashing the binary to the SD-Card? Which tool can I use?

Thanks in advance!

There is a test code (without any OS) for i.MX53QSB called IMX53_QSB_OBDS .  You can download it from the i.MX53QSB web page.
