OK.  Thank you for your testing.  I am guessing that you didn't use Cleanflight V1.10 erase_flash, so someone still needs to test that.

Ok . This is hw error I think. I will check some of these . If I have not find anything else.I will buy a new board. I will use it with 15.09. I am not clear about 16.09 fw. Thank you for your information.

It is interesting that flash_info says that size is zero.

BF says your fw not support to logging.
In your flash_erase test did you use the exact Cleanflight GCS and firmware version (V1.10) from successful user pointed at by @f5soh?

(Since you already replaced the flash chip) It seems that one of these is probably true:
- solder blob
- connection not soldered
- bad / broken trace
- incorrect board traces design
- bad CPU chip
- wrong or missing components (such as flash CS pullup or voltage regulator)
- your version of BF does not access the external flash chip
- bad voltage regulator

After using Cleanflight V1.10 I would probably use CC3D schematic and a volt ohm meter to check the CPU to flash connections (or I think you maybe already did) and a few other things like flash CS pullup value (R17 should be 10K) and VCC.  CC3D schematic can be found at "hardware/Production/CopterControl 3D/CopterControl 3D Schematic.pdf"

(not saying the following is the problem, just information for you)  Some Sparky2 FC boards have a problem with baro chip.  It turns out that the reason is that clone board maker used different voltage regulator.  That would have been OK, but the different voltage regulator needed a different capacitor for it's precision voltage reference source and made bad power with the incorrect capacitor.

Erasing flash using the ST-Util do nothing to the 2516 flash device i think, only CPU related...
BF flash erase will format the 2516 device, if you look the post i linked this solved the issue.

Hi I am writing this for the f5soh user. You give an procedure to me for erease the flash under BF. I have a `st flash loader` utl. Before I load the fw by this utl I erease the flash more 10 times. I think This is same with the BF flash erease. İf you are thinking not same. I can do it again with BF.

Another test:
On the vehicle tab I made a simple Car configuration.One motor and one servo. I saved. nuturaly red x. I dont care it. I continue with output conf. I saw motor and servo slider came to the output tab. I made a min max setup.And I saved .
I have red x again on the save button. I dont care it. I connected esc and servo to the configured channels.On the output tab. I clicked live test. I tested the sliders for the motor and servo. Motor and servo running without problem. I can say this an saving to flash isue. Who created this İsue . I dont know.May be Fw maybe Murphy. I hope Murphy do it. I will change cpu next week. Because i changed flash before. I checked flash leg connections all is ok.

BF says your fw not support to logging. I am using 3.2.5 betaflight fw.

Look this post for 'flash_erase' command, using CLI console.
