maybe your chip need more time to earse. like W25Q32VSIG needs 7s to finish earse at least. you can add tpw more. and operate step by step: erase runs single.check blank after finished. if blank is ok,select menu "run"--"program". we test earse unfinished by vp290 if tpw=5ms.it is only 3s-4s. if it can not be work,you can change vcc to try.like 2.7V. send screenshot to us, weilong@weilei.com.cn
