My target board( use K40DX256 chip) connecte to Kinetis KWIKSTIK-K40 board by JTAG,use IAR software .After I downlord a grogram,let target chip into VLPS mode,I don't download grogram to target from IAR again(I try disconnect target board power,remover Kinetis KWIKSTIK-K40 form PC). The information from IAR J-link is Fail to get CPU status after 4 retries Retry? It seem JTAG can't recover chip from VLPS.How I can do ？thanks.
