I encountered the following problem:
I use 2 Cameras (A480, FW 100b) and 2 16 GB SD cards with CHDK 1.3 (both Kingston, same type)
Cam 1 + SD 1 works fine
Cam 2 + SD 2 works fine
now changing the cards
Cam 1 + SD2 works fine, as could be expected
Cam 2 + SD1 does not work!
When starting CHDK by updating firmware this message is shown:
"ERROR. MISSING MODULES"
The original Cam firmware shows "Memory Card Error"
I tried a lot with SD1, formatting (Windows, CardTricks, in the camera), erasing (SDFormatter). Nothing helped.
Anyone an idea what's the reason?
PS: Checked the Card with two further A480 --> works.
