Hi all,Thanks for your replies. Currently, I don't understand about DDRAM of K70. Do I need configure DDRAM session in linker file, or doing somethings with DDRAM? K60 board does not have DDRAM, so where kernel will be loaded when booting?ote
You shall need linker script with a region and section for DDRAM indeed. Also you will need some code for initialization of DDR controller and possibly DDRAM chip.

2012/1/4 Morris, Richard <Richard.Morris@xxxxxxxxxxxx <mailto:Richard.Morris@xxxxxxxxxxxx>>Hi All, Regarding using J-Link and Ecos. I use J-Link with eCos and ARM processors. I have used it with the Kinetis K60, the NXP LPC2xxx family, Atmel AT91SAM family. My configuration is: Ubuntu Host 10.04 Eclipse 3.6 Zylin CDT Plugin (http://opensource.zylin.com/embeddedcdt.html) GCC compiler: provided with eCos or CodeSourcery's Segger's GDB Server (running on Linux or Windows) Segger's J-Link and/or J-Link Pro Regards, Richard On Jan 3, 2012, at 6:01 AM, Ilija Kocho wrote:Hello Linh Thank you for your interest in eCos for Kinetis. First I would invite you to post your comments and questions to some of eCos mailing lists: http://ecos.sourceware.org/intouch.html The benefit is both for community and you, for instance I have no experience with J-Link, but somebody else may have. Regarding your attempt to run eCos on K70, apparently you are luckier than me :) as you already got a K70 tower. I am waiting for my K70 tower so I haven't been able to play with K70 so far, but from K70 RM I can assume that variant HAL may need some changes (Clocking, etc.) in order to become compatible with K70. Regarding your code: I would avoid changing variant default settings, you can achieve similar effect by stating requirements in platform HAL, Please look at K40 CDL.

The attach files are patch for TWR K70 and eCos config file for k70-redboot. Redboot for K70 can build, but it can not run after download by IAR workbench through J-Link. Can you spend some free times to get overview on it, then give me your comments please. Thanks so much and have nice week. I'm looking forward to hearing from you.
