CAT28C512 Programming failed!

How can TL866II plus program CAT28C512? I tried 4 pieces of CAT28C512, all failed, and the result was the same as the picture.

Steps:
1. open a file and try to write to CAT28C512, the verification failed;
2. Read the content of CAT28C512, and found no change as before programming.

1.write

升级到11.20 ,11.10有个写保护问题
在11.20测试了,只是引脚检查功能错误,忽略一下就可以了,编程没有问题的,
下个版本修正引脚检查的问题:
