As we are working in ARM11 board which has ECOS and redboot as the bootloader in the BSP, we have to monitor the battery through one wire device protocol in the redboot.Can u please help me, how to program the ECOS for the one wire protocol to access the battery EEPROM.Also as iam a newbie for ECOS and redboot,please show me some link or documentation where i can start to achieve this.

If you desire to contribute the common one-wire device for eCos, I would refer you to http://ecos.sourceware.org/docs-latest/ref/ecos-ref.html http://ecos.sourceware.org/docs-latest/ref/io.html If you already did implement the same primitives, for example, as described here http://www.maxim-ic.com/appnotes.cfm/appnote_number/126 , you can easy add new polled device (your 1-wire device) for RedBoot using the RedBoor_idle() register, for example RedBoot_idle (read_ow_device, RedBoot_IDLE_AFTER_NETIO); void read_ow_device (bool is_idle) { if (!is_idle) return; // call your procedure ... } I did play with that maxim source 'as is', just defined those A-J values for my target. It did work fine (one my eCos thread measured a temperature arround the board). And the last note: please, don't use interrupt driven 1-wire read in RedBoot. -- Sergei > > Thanks in Advance > > -- > Best regards, > Sivakumar.R.J > -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss ^ permalink raw reply [flat|nested] 4+ messages in thread

Did a supplier give you any sources? Certainly, you need in the toolchain and sources to release own RedBoot. I just did tell you how to organize a polling in RedBoot (that was a common question, i.e. the question wasn't the target specific thing). -- Sergei P.S.
