RE: [ECOS] kinetis kwikstik's ecos trouble

[tangwei <tziang@hotmail.com>]

Thanks, I have used the Makefile provided with examples,now they can run successfully.
but when I want to try a example,I must use J-LINK to download the binfile into kwikstik's flash.
Is there any easy methods to do this by the redboot,such as use the redboot's load command,
first load the file into RAM,then use the redboot's go command to execute the example app,
if the app work successfully,then use J-LINK to download into flash.
I have try this way,setp1. download redboot ROM startup for Kwikstik,and get the below info when redboot startup
Platform: Freescale KwikStik (Cortex-M4)                                       RAM: 0x1fff8000-0x20007000 [0x1fffb6a8-0x20007000 available] 
step2. download the example app twothreads.bin,use
RedBoot> load -v -m ymodem                                                     CCUnrecognized image type: 0x20008000                                          xyzModem - CRC mode, 4(SOH)/0(STX)/0(CAN) packets, 4 retries 
then tryRedBoot> load -r -m ymodem -b 0x1fffb6a8                                       CRaw file loaded 0x1fffb6a8-0x20000ae7, assumed entry at 0x1fffb6a8            xyzModem - CRC mode, 172(SOH)/0(STX)/0(CAN) packets, 4 retries                 RedBoot> go -c 0x1fffb6a8                                                                   $T050f:a8b6ff1f;0d:e86f0020;#5c
both seems fail
