我的 4GPY2XF sys 闪灯,没有TTL输出,示波器查看flash sclk,仅仅有一次时钟,好像是没有reset或者没有读取到flash的内容。 拆下来flash编程器读写正常。请教下维修思路。
I have SKS3200M-4GPY2XF with sys blinking without any output at TTL. The TTL connection is ok on the PCB. Measured SCLK of FM25Q16 there is only one time waveform and then nothing. How to debug it?
