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.
Solved! Go to Solution.
i can't use EraseAll command on chip,because i can't connect JTAG(SWD), the chip power current only 5nA@3.3V, could you tell me another way to make JTAG(SWD) connection? And could you tell me how can boot not form flash?did it support boot from RAM?
