I am new to RLink and have problem in STR712FR2 flash writing.
First, erase works fine but in blank check procedure, RFlasher says "Flash is not blank, Section between 0x40000000 and 0x4003FFFF is not blank."
Data dump shows the area is filled with FF but after flash reading, data dump shows the field is not erased.
I have no idea why this happens. After writing flash, It seems that flash is not written at all.
This seems to be associated with the fact that flash area (0x40000000 ~ ) is aliased to 0x00000000 area.
And another question, Why reading flash is much slower that programming flash.
Please answer.
Thanks.
