Hi,=

Anyone ported Barebox to Freescale’s i.MX27PDK 3-stack = ?

I’m new to Barebox (o= r any bootloader…) and I try to port it for my i.MX27PDK, but did not= succeed yet. I don’t get anything on the console port yet.

I took the i.MX27ADS as a reference, c= opied all its files to a new board directory, and started adjusting the fil= es. Via the debug board of the i.MX27PDK (containing a CPLD), I should be a= ble to turn on some debug leds very early in the boot process, but even thi= s did not succeed (yet…). I made changes in board_init_lowlevel() of = lowlevel_init.S to initialize the hardware. I guess board_init_lowlevel() i= s one of the first functions that is executed. Correct ?<= /p>

Because I didn’t get it up and running, I= tried to do debugging with a PEEDI debugger. Anyone experience with it for= debugging Barebox ? I’m using PEEDI in combination with Eclipse (Zyl= in) debugger. It looks like I have problems when trying to step in assemble= r sources…

<= /o:p>

Any help welcome…=

As a first step I would try to use barebox as a second stage loader behind U-Boot or redboot or whatever is on your board. What do you have on your board? When using barebox as a second stage loader you can comment out everything in board_init_lowlevel. Provided that you are using the correct UART you should see something at this stage. What silicon revision do you have on your board? Our i.MX27ads is rev 1 which has some incompatibilities to other revs, so maybe this is where it breaks. Also, make sure that the SDRAM setup fits for your board. For the lowlevel setup you might want to look at Freescale provided sources.

Our design was based on the IP-Cam, and I was able to get the I2C,Ethernet, and the HS USB port running. I found the hardest part was getting the PLL config work right. I finally just commented it out and let the defaults take over. There are some nice ports already and I would suggest looking at the systems part of Barebox already. Also start simple, disable everything! Even tho the board has all the hardware, don't include it in the beginning. I disabled USB,Ethernet,Display,I2C, and it helped a-lot. After serial, I would add Ethernet if you are using it. I was simple as turning it on. You will need to configure your MAC address. ;-) As for debugging, I use a cheep olimex arm-usb-ocd (didn't have access to the JTAG debuggers at work). Remember you have to setup your ram before sending code to the board. As for a debugger, used gnu tools and for the IDE I used insight. I run under Ubuntu and compiled the tools from source. (bintools,gcc,gdb, insight) Hope it helped. James _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
