ASA5505 cannot boot from image

Hi Expert
ASA5505 cannot boot from image. After power on the asa, it cannot find the image. I uploaded the image through console(this is only way that I can enter the asa), and the uploading is successful. However the situation is the same as before uploading ios. So the asa is always  trying  to boot, but it cannot find the ios. The ios keep the process and never stop.  The following is some commands that i used for uploading ios and some error message after I uploaded ios.  Any expert can give some suggestion ? Thank you

Alan Huseyin KayahanCommented:
Once TFTP finishes in rommon, ASA should load it up into memory. After the loading, if you restart the ASA without copying the image to disk via copy command, you will again fall into reload loop.

If ASA could not load the image up to memory and boot right after the tftp finishes, then one of the following could be the case

a) The image version is beyond what ASA5505 can support
b) The resources (disk, ram etc) is insufficient for that particular image
c) You are using an OEM flash drive or RAM
d) The image is incompatible with the hardware architecture (32 or 64 bit)
