Small trick SPI flash programming.

Post by usbbdm »

I have found a small trick when I try to erase and program FL256SAIF00. The erase is not consistent. Sometime it stuck at erasing and what I found is I need to add a capacitor between 3.3v and GND close to the chip. (330uF).
Once I did that, the erase is 100% and stable.
So if you have issue erase chip, consider add a capacitor.

Here is the picture I put the capacitor on DSCN2516.JPG.
It would be better to solder the capacitor at the end of the clip itself. DSCN2518.JPG.
Make sure the - pin should be soldered to GND.
