Problem on flash access?

[jerryXCORE]

I got a problem to access flash

Code: Select all

int value, psize; fl_BootImageInfo b;
value =fl_connectToDevice (SPI , myFlashDevices , sizeof ( myFlashDevices )/ sizeof ( fl_DeviceSpec )); printintln(value);
psize = fl_getPageSize ();  printintln(psize);
value = fl_getFactoryImage (b);  printintln(value);
value = fl_getNextBootImage (b); printintln(value);

* A few month ago, everything is ok.
* But now:
--- fl_connect() return zero: means success
--- fl_getPageSize () return 256: means success
--- fl_getFactoryImage() return 1: means fail
--- fl_getNextBootImage() return 1: means fail

How could it be, any hint?

There's a rather obvious explanation - you have no valid boot image or upgrade image resident in the flash.

Although I'm sure you already thought of this... Does it boot from flash OK using the current image?

Yes, you right! I misunderstood the flash logic:
* I erased all image accidentally by using fl_startImageReplace().
* But I though there should be at least one image remaining.

Thank for your hint!
