[U-Boot-Users] Motorola PPC827x

Yuli, I have a PQ2FADS_VR ( ppc8275 ) board from motorola which has a 66000000 Hz clock. Is it worthwhile to insert this anomaly to the u-boot code? I have done changes in MPC8260ADS.h file in order to make it run for me.

Matias> Can you explain me where the code for PPC8270 resides in the Matias> file structure? First of all, download the latest version from CVS (0.4.7 or CVS HEAD). Differences between 8260 and 8270 do not justify creating a separate CPU directory. In fact, all the differences result in some 10-20 lines of code, so look at cpu/mpc8260. Use `grep' to find HiP7 and you'll see the changes I made to support 8270/75/80. The same is true for PQ2FADS. I ported U-Boot to this board but since it's very similar to older MPC8260ADS I modified existing port to support all Motorola evaluation boards (MPC8260ADS/MPC8266ADS/PQ2FADS). Some differences are handled by #ifdefs. Cloning an existing port and changing ten lines to support new board as it's done in many cases creates maintenance nightmare. So the right place to look is board/mpc8260ads. BTW, I think it's mentioned in README.

Merged and tried, and works as expected on my ARM board. Thanks for the effort. What prompted the jump to 1.0.0 ?

[U-Boot-Users] Passing clocks to Linux (ARM)?
by Steven Scholz 31 Oct '03

31 Oct '03

Hi, Looking at the kernel source for AT91RM9200 cpus shows that the clocks for processor and bus are hardcoded. So for instance baudrate generator is programmed with some hardcoded value. I know that MPC8xx passes the clock values (and much more) from U-Boot to the Kernel. Has someone done that for ARM cpus? Is there a plan to extend bd_t structure for ARM as it is for PPC? Thanks. -- Steven Scholz imc Measurement & Control imc Meßsysteme GmbH Voltastr. 5 Voltastr. 5 13355 Berlin 13355 Berlin Germany Deutschland fon: +49 30 467090-0 Tel: 030 / 467090-0 fax: +49 30 4631576 fax: 030 / 4631576

Hi, Works very fine on a PQ2FADS-VR board. Going to port it further to a custom board we are developing. What shall I do with the changes/modifications we are doing for our custom board? Shall I send the ported U-boot to you Wolfgang? I have a GPL splinter in my mind ...

Hi Jacob, I found out the hard way by debugging and reading the source (the all important hint was a comment in board/wepep250/wepep250.c). BTW, it was quite an "interesting" task, since I did it on a freshly developed board (with hardware bugs, as it turned out!)... Cheers Anders

RE: [U-Boot-Users] omap5910
by Woodruff, Richard 30 Oct '03

The 5910 for all practically purposes is the 1510. I have seen a doc somewhere, not sure if I captured it or not. Basically, the difference is the way the parts are tested and sorted. The 1510 parts are speed rated, and you can get up to a 168MHx part. The 5910 parts are not and its only guaranteed up to 150MHz, but its likely many will run at 168. The 1510 also "claims" support for some functionality which the 5910 will not admit to having. The issue there is support and validation. 5910 parts will not be validated for everything a 1510 will be. I use a mix of both types of chips on development boards. I use their u-boot images interchangeably....I have set my timings back to 150MHz as the thing I've been working on will get parts stamped as 5910 not 1510.

I corresponded with a couple people who use bdi2000 on omap. If you read around on some news archives you will find them. George Davis is one who comes to mind.

Has anyone done any work for the omap5910 cpu for u-boot? I understand its extremely similar to the omap1510 cpu. Does anyone have any code or pointers to how the two cpu's are different? Thanks, Matthew -- Matthew S. McClintock <mattsm(a)arlut.utexas.edu>
