The issue hasn't > been solved yet. Any hints are appreciated. I have tried with removing the test for timeout in the write_data() routine, just looping on the status: while (((status = *addr) & (FPW) 0x00800080) != (FPW) 0x00800080) ; This worked fine for large amounts of data so the timeout value is probably too low. Let me know if this is the same with your setting. Regards, Philippe

[U-Boot-Users] Stand alone app for changing MAC address in SMC91C111
by Robin Getz 12 Jan '05

12 Jan '05

I have created a stand alone application to change MAC addresses in the EEPROM attached to the SMC91C111, as well as the following commands: - P : Print the MAC address in the EEROM and MAC - D : Dump the LAN91C111 EEPROM contents - M : Dump the LAN91C111 MAC contents - C : Copies the MAC address from the EEPROM to the LAN91C111 - W : Write a register in the EEPROM or in the MAC It can be reviewed at our u-boot (based on 1.1.1) cvs for the Blackfin BF533 processor at: [sorry for the long url, but what can you do?] http://cvs.blackfin.uclinux.org/cgi-bin/cvsweb.cgi/u-boot_1.1.1/examples/?c… added: smc91111_eeprom.c README.smc91111_eeprom Based on people's feedback, I will submit as a patch to this list. One questions: 1) should READMEs for stand-alone applications stay in the examples dir, or go in the doc directory? -Robin

[U-Boot-Users] [Patch] Support for AMD db1550 board
by Leif Lindholm 10 Jan '05

10 Jan '05

Hi This patch adds support for the AMD db1550 board to u-boot. It is implemented as a flavor of the au1x00 family. Since I have not tested the pcmcia/ide stuff, this board has CONFIG_BOOTCOMMAND and CONFIG_COMMANDS ifdef:d to different values than the rest of the boards in the family. Also, the memory setup differs a bit from earlier boards, due to this board being equipped with DDR SDRAM. This has lead to quite a large memsetup.S (heavily ifdef:d). It also includes some code taken from AMD:s version of YAMON for this board (with their permission), for enabling cache and doing some preloads before reconfiguring the flash controller to correct values. This precaution may be a good idea on the other boards as well, but since I have not tested it on them, this part is ifdef:d CONFIG_DBAU1550. I have included the "new" version of mkconfig, which now accepts a "$6" specifying endianess. This software is only tested in little endian mode. This patch also contains some minor changes allowing for setting CPU clock frequency in only one place (instead of three) and calculating the correct divisor for the uart based on this. regards / Leif

It is not a problem with the toolchain, it is due to the fact how the makefile in examples is written. When you first run make without arm-linux-gcc in the path make does a lot, but it created only empty .depend files (because of compiler not found). Afterwards you include arm-linux-gcc in the path and run make again. Everything is running then except the examples directory. Make does not compile hello_world.c, instead it uses a builtin implicit rule to make hello_world (there is no dependency from OBJS and the explicit dependency for hello_world.o is missing, because of empty .depend). When you run make -r (no builtin implicit rules) it works. Work around: make clobber (deletes your wrong .depend) mkconfig ... adding arm-linux-gcc to your path make Hint to Wolfgang: If you add OBJS to the all rule in Makefile for examples, it will work in any case. all: .depend $(LIB) $(OBJS) $(SREC) $(BIN) Rainer
