Jan 17 08:34:12 <aproemel> hi together, i've got a problem with my ATMEL AT91RM9200
Jan 17 08:34:24 <aproemel> does anybody has any expirience with this device ?
Jan 17 10:11:26 <vmaster_> aproemel: what kind of problems?
Jan 17 10:12:11 <aproemel> I've created a asm starup (with KEIL IDE) and wrote a small function that should toggle port B
Jan 17 10:12:34 <aproemel> If i upload the hex file to the prozessor with XMODEM nothing happens
Jan 17 10:12:44 <aproemel> I don't have a JTAG Debugger
Jan 17 10:13:22 <aproemel> I'll explain what i want to do
Jan 17 10:13:40 <aproemel> I build a own board, only prozessor, SDRAM and Serial Interface
Jan 17 10:13:56 <aproemel> with this board i want to test the SDRAM interface
Jan 17 10:14:24 <aproemel> i haven't spent Flash to the board, so i'm not able to use uboot
Jan 17 10:16:53 <vmaster> aproemel: you're using the AT91RM9200's buildin bootloader?
Jan 17 10:17:00 <aproemel> yes
Jan 17 10:18:21 <vmaster> and which tool did you use for the upload?
Jan 17 10:18:41 <aproemel> CuteCom with XMODEM protocol
Jan 17 10:20:58 <vmaster> you said you tried to upload the hex file - i believe the bootloader expects a plain binary
Jan 17 10:21:53 <aproemel> mhh, maybe thats my fault
Jan 17 10:22:02 <aproemel> do you work with a AT91RM9200 ?
Jan 17 10:22:12 <vmaster> i used to work with one, but I never used the builtin bootloader
Jan 17 10:22:36 <aproemel> you had u-boot in flash, or ?
Jan 17 10:22:38 <vmaster> anyway, the bootloader definitely expects a binary file
Jan 17 10:22:39 <vmaster> yeah
Jan 17 10:23:00 <vmaster> and I had JTAG (my own JTAG debugger, OpenOCD)
Jan 17 10:24:02 <aproemel> mhh, well a Jtag Debugger would be nice, i've to talk to my boss, that i'll get one
Jan 17 10:51:01 <aproemel> vmaster: did you build your board at your own? or was it a Demo Board like the one from ATMEL ?
Jan 17 10:53:42 <vmaster> I only worked with a CSB337 (cogent). Originally my university wanted to design a board of their own, but this was never completed.
Jan 17 10:54:56 <vmaster> what are your long-term goals for the AT91RM9200? Linux?
Jan 17 10:56:16 <aproemel> I've to build a own board, and have to do a linux adaption
Jan 17 10:56:19 <aproemel> ist my Diplom Arbeit
Jan 17 10:57:06 <vmaster> ok, so you'll end up using the GNU tools anyway, right?
Jan 17 10:57:14 <aproemel> sure
Jan 17 10:57:23 <aproemel> my toolchain works fine with the embest demo board
Jan 17 10:59:03 <aproemel> but i haven't found a documentation which parameters i have to use for gas to compile my startup assembler file
Jan 17 10:59:13 <vmaster> regarding the JTAG debugger (you said you'd have to ask your boss): You can use inexpensive hardware (Wiggler, FT2232 based USB dongle) with the OpenOCD (which is free/open software)
Jan 17 10:59:45 <aproemel> mhh, what shall it cost?
Jan 17 11:00:09 <aproemel> that i can tell him a price on friday
Jan 17 11:00:31 <vmaster> I don't think you need any parameter for gas at all - just a linker script, that tells the linker (ld) where to put your code and data
Jan 17 11:00:42 <vmaster> you can build a wiggler yourself for around 10€, I suppose
Jan 17 11:00:47 <vmaster> You can get one ready-made for ~20€
Jan 17 11:01:33 <vmaster> The cheapest USB based dongle is 29€ (+ VAT and shipping from .ch)
Jan 17 11:02:19 <aproemel> well, <200? for all ?
Jan 17 11:03:20 <aproemel> what do you thin about this device: http://www.amontec.com/jtagkey.shtml
Jan 17 11:04:05 <vmaster> I have one on my desk - but it's only worth the money if you're considering non-3.3V devices
Jan 17 11:05:25 <vmaster> if you just want to use it with the AT91RM9200 you can do with the much cheaper JTAGkey-tiny
Jan 17 11:05:57 <vmaster> you'll have to use the OpenOCD with all FT2232 based dongles (Amontec JTAGkeys, Olimex ARM-USB-OCD, Signalyzer, home-made)
Jan 17 11:06:15 <vmaster> Rowley's CrossWorks will support them with the next release, too
Jan 17 11:06:46 <vmaster> the OpenOCD is quite stable, but as most of the free tools it's not as easy to use for a beginner as the commerical ones
Jan 17 11:06:53 <aproemel> well, if the JTAGkey-tiny works with my AT91RM9200 everything will be fine
Jan 17 11:07:17 <aproemel> is there good docu fpr OpenOCD ?
Jan 17 11:08:23 <vmaster> there's an active forum at sparkfun.com and a Wiki explaining most of the config options and commands at http://openfacts.berlios.de/index-en.phtml?title=Open_On-Chip_Debugger
Jan 17 11:08:23 <vmaster> the manual in the berlios files section is outdated
Jan 17 11:08:38 <vmaster> the major problem for a beginner is getting the .cfg file right
Jan 17 11:10:22 <aproemel> well, i think i have to try it
Jan 17 11:11:36 <vmaster> it's by far the cheapest solution, and I've used it for exact the same job - getting U-Boot and Linux to run
Jan 17 11:12:09 <vmaster> other JTAG debuggers are >200$ and require the use of software >1000$
Jan 17 11:12:15 <aproemel> ok, then i'll do so too
Jan 17 11:12:15 <aproemel> :-)
Jan 17 11:12:28 <aproemel> i think <200? wont be a big problem
Jan 17 11:14:42 <aproemel> thanks for your help 
Jan 17 11:14:57 <aproemel> I'll tell you if it works :-) if i get such a debugger :-)
Jan 17 11:17:01 <aproemel> vmaster: one question about your work
Jan 17 11:17:28 <aproemel> did your write anything in assembly language ?
Jan 17 11:18:38 <vmaster> the low-level startup files for u-boot
Jan 17 11:19:11 <aproemel> would you tell me your gas parameters?
Jan 17 11:19:55 <vmaster> U-Boot sets them globally, I didn't have to change anything
Jan 17 11:20:11 <aproemel> aahh, ok
Jan 17 11:20:16 <vmaster> search the web for Jim Lynch's tutorial
Jan 17 11:20:40 <vmaster> on using the GNU tools with Eclipse to program Philips LPC2000 (ARM7)
Jan 17 11:21:19 <aproemel> http://gnuarm.alexthegeek.com/
Jan 17 11:21:23 <aproemel> i think you mean this
Jan 17 11:22:07 <vmaster> mhh, yeah, but I think that's the big package with all the software, which you don't need
Jan 17 11:22:24 <aproemel> i download it, an look what i need, and what not 
Jan 17 11:24:50 <vmaster> he has an example using a .S startup file, a .c main file, and a linker script
Jan 17 11:25:33 <aproemel> that is great
Jan 17 11:29:09 <aproemel> http://www.olimex.com/dev/pdf/ARM%20Cross%20Development%20with%20Eclipse%20version%203.pdf
Jan 17 11:29:17 <aproemel> found the pdf
Jan 17 11:29:50 <vmaster> yeah, version 3 is slightly older, but the gas/ld stuff should be the same
Jan 17 11:30:14 <aproemel> i'm searching for a later version then
Jan 17 12:20:47 <nm> re *
Jan 17 12:23:20 <nm> Hi all, can openocd run on Linux platform ?
Jan 17 12:39:26 <aproemel> vmaster: do you build your toolchain at your own?
Jan 17 12:39:46 <aproemel> or do you used something like "crosstool" from dan kegel or "buildroot"
Jan 17 12:47:57 <vmaster> nm: yes, that's what i wrote it on. Support for Cygwin, native Windows and FreeBSD was added later
Jan 17 12:49:01 <vmaster> aproemel: I've used binary releases (ELDK from denx), toolchains built with crosstool and built on my own
Jan 17 13:52:51 <aproemel> vmaster: thanks
Jan 17 15:31:45 <[g2]> vmaster rocks! :)
