Q: DE0-Nano-SOC 固化EPCS时提示

209040 Can't accessJTAG chain
209014 CONF_DONE pin failed to go high in device 2. make sure all communication cables are securely connected. select a different device. check the power on the target system or make sure all nCE pins are connected to GND



A:

客户手头有 EPCQ64 和 EPCS128两种DE0-Nano-SOC,由于两种Flash的容量存在差异,若使用EPCS128的配置文件对EPCQ64进行配置,则可能出现无法正常固化的情况,请客户在固化前对板卡上的Flash型号进行确认,使用EPCQ64的JIC对两种Flash均能正常烧写,使用EPCS128的配置文件,则只能对EPCS128进行烧写。其中封装较大的为EPCS128,封装较小的为EPCQ64。
