Nishanth' tech rambles

Just started off with uboot-v2 port on my "unamed" board. My objectives: a) get uboot build to work from SRAM with basic uart support, probably usb later on if i can port the gadget driver from linux kernel. b) configure clocks and get SDRAM up and running. c) attempt kernel bootup - now, this i expect to be a pain... d) support nand e) support nor, and get support for SDP (low in personal priority currently - but should be a no-brainer hopefully). Schedule is going to go thru one file a day(or atleast a week depending on my "office work" load).. Today is going to be start.s lets see if we can get a concensus or flame war on the list.. this is critical as most boards share the same code.. as long as it is V4 ISA, things should be fine.. I would not dream of thumb in this peice of code.. by the way, Sascha Hauer is the custodian for uboot-v2 as I was told on the uboot irc.

Folks who have CSST know the capability of OMAP doing something known as a peripheral boot mode support over USB and UART. on Linux, well.. looks like no one(at least to my knowledge) has done the same thing.. So, today, in the middle of cooking some kadai chicken and some chicken kebobs, i played around and got thru to give a proof of concept code( http://www.geocities.com/crecmca98/Linux/omap_linux_peripheral_boot.tgz ): 1) “Hacking” to get the vendor id and product id: I dont own a Catc or a usb monitor.. so just plugged in the board to my laptop and dumped the syslog ;) $ cat /var/log/syslog Mar 16 15:26:23 coyote NetworkManager: [1205699183.236191] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/usb_device_451_d009_N/A'). Voila!! 3430 is nothin but, VendorId = 0x0451 DeviceID = 0xD009 2) Trigger an external program to download image: Would you believe it, last time i was working in the kernel, hotplug was still working.. i...

Love the concepts out in the last few weeks.. been busy with a bicycle.. anyways.. check these out: http://www.reuters.com/news/video?videoId=77483&videoChannel=6 - a lifeOS+ the sensory network.. The real one: Morph from Nokia and Manchester univ.: http://www.reuters.com/news/video?videoId=77681&videoChannel=6 Some thing to moot on -> nano tech and capabilities that it brings in.. wearable computing, technology more integrated with humans.. sounds like science fiction.. but a bit of Google later on specific tech.. we might be surprisingly closer than expected...
