I download wrong HEX file into CY8C4247LQI-BL483 chip, then the chip cann't connect to JTAG.

   

i measure the current and find the chip current is 6mA when power on(very short time), then drop to 5nA, and never up. 

   

hex file name: "PRoC_BLE_CapSense_Slider_LED" form demo program.

   

download tools: J-Link

   

Download software: J-flash

   

Downloade interface: SWD

   

please help tell me how to connect JTAG(SWD mode) and erase chip, thanks.

Hi,

   

CY8C4247LQI-BL483 provides EraseAll command on SWD. Can you try that ?
