USE CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit to program another ble chip

[algic_767251]

Hello.

   

I started a new BLUETOOTH project and so I choose the Cypress solution. Last month I started doing some experiments with "CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit". Good examples. Now I would like to program my board using the kit programming pins (see j11 connector). The microcontroller on the board is the cy8c4127lqi-bl473. Unfortunately the psoc-creator and the psoc-programmer not recognize il chip. What should I watch inside the board ? Best regard. Alberto

Hi Alberto,

   

From the problem description, it seems like the device cannot be acquired in Programmer. Can you share the schematic of your board? Did you connect any external voltage to the VCCD Pin? If so, please remove it.

Hi,

   

on pin VCC I connected a capacitor of 1uF ... below my scheme...

   

I forgot to mention that the power pins have already 'inverted them as your specification.

   

Best regards

Hi BMAH,

   

I have found the problem... for routing problems the SDAT-pin was reversed with the SCLK-pin ... so now it works.

   

Best regards
