I also tried 60 delay. Still nothing. You should see some U-Boot boot messegas reagardles what boot delay you configured. Maybe your clock configuration is wrong (wrong baudrate). Or the SMDK2410 uses another serial interface as console as your board? Or the SDRAM configuration is not suitable for your board. Or, ... there are many things that could go wrong. Unfortunately thers is no quick way to port U-Boot to a new hardware (see the "U-Boot Porting Guide" section in the README in the U-Boot source tree: http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=blob;f=README;h=5cbe7c… :-) > Perhaps I'm expecting the wrong result from u-boot? Is the SMDK2410 > default config supposed to give a prompt at all or go straight to DHCP > et. al? It was some time ago, I last used the SMDK2410. But I'm pretty sure, that it prints some boot messages. You should see this messages regardles if you boot from flash, ethernet, or whatever. Please keep the list on cc. Regards, Martin

[U-Boot-Users] [PATCH v2] net: make ARP timeout configurable
by Guennadi Liakhovetski 03 Apr '08

03 Apr '08

Currently the timeout waiting for an ARP reply is hard set to 5 seconds. On i.MX31ADS due to a hardware "strangeness" up to four first IP packets to the boards get lost, which typically are ARP replies. By configuring the timeout to a lower value we significantly improve the first network transfer time on this board. The timeout is specified in milliseconds, later internally it is converted to deciseconds, because it has to be converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on different boards.

[U-Boot-Users] [PATCH ARM/AT91 0/6] AT91CAP9/AT91SAM9260 cleanups
by Stelian Pop 03 Apr '08

03 Apr '08

Hi, The following patches do a few cleanups for the AT91CAP9ADK and AT91SAM9260EK boards: - enable handling of 8 or 16 bit NAND memories - set the SPI clock to 15MHz (like Linux does) - set bootargs to sane values so that Linux boots out of the box in the supported configurations. Please apply, Thanks, Stelian.

[U-Boot-Users] New Image format: headers hashes.
by Luigi 'Comio' Mantellini 03 Apr '08

03 Apr '08

Hi Guys, I ask you fro a comment regarding the new image format. I'm studying the mkimage code (and image.c file) to understand how new image works. I have the following observations/questions: - The mkimage calculate hashes before that timestamp is added to image. is it better exchange the order of these operations (before add timestamp then calculate hashes)? - Does the new format assure that the complete image (_all_ sections, images, ramdisks, configurations, blobs) are covered by at least an hash value? should mkimage add at least a hash value for the root node?
