Question : Error - Device not found on control center
We made over 100 sets with FX3 chips.
but Only 2 sets is unable to download our program.
We are using only EEPROM by I2C.
I set PMODE F1F. (I2C boot , but if failure, usb boot)
First of all, they (bad samples) can't boot through USB.
And, if i set PMODE F11. boot is succeeded throgh USB boot.
( I can see "Cypress boot loader" on Control center)
but if i try to download a firmware by control center, Error is occured which is "Device not found".
(emaulate -> Device not found, It didn't show the window for selecting a file.)
I was checked several points on hardware (voltage, etc). but there is not a problem.
why is it happend? please let me know anything abut it.
