Well hello everyone. I bricked my NAS. My NAS is Planet-7201 2bay sata, based upon Cortina CS/SL3516 (c3),16mb Flash and 128mb Ram, 1Gb marvell based ethernet phy).
http://www.youtube.com/watch?v=3AqanxvE-Ng (this is how the device looks).
Original firmware sucked very badly so I started my research for alternative firmware for 3516, BTW(if anyone would want to test my org firmware I have a backup of it even with RedBoot bootloader 16M+128MB on
http://www.bitmex.pl/nas7201). First i Upgraded my device to (Mr. EmAns (that was his name, I guess) firmware (it was modified Raidsonic 4220 firmware with rsync, ssh support and much more). Lately I wanted to switch to try some firmware still in development based on OpenWRT.
http://opengemini.free.fr/wiki/doku.php?id=start. From device Ui site I tried to uplaod the firmware for Planex device by loading sysupgrade image. Device flashed but wasn't working so I entered a bootloader console that still was available/working. I tried loading a firmware by pressing (bad decission) the magic X - upgrade firmware button. Than I loaded an image (binary for redboot update). Now I can't access the RedBoot anymore. I guess it's dead cannot access from TTL serial console anymore. Propably will need to do JTAG and load RedBoot
asking kindly for support
I have an images of the PCB of the device these pictures are kind a in high resolution more than 200kb attachments upload limit so they are available at the external link
