Please note the write buffer size of IS29GL128/256 is same as S29GL128/256P (64 bytes) which is two times bigger than S29GL128/256N (32 bytes).
And also there are two things to be optimized for software 20180630 version.
1) RD/BY# pin condition: The RD/BY# signal after erase command is going intermittently to high and back to low soon even before finishing erase operation with S29GL256P algorithm while keeping low until finishing erase operation with S29GL256S algorithm. (There should be some condition difference for RD/BY# pin between S29GL256P and S29GL256S erase algorithm.)
2) Contact check routine. The reason is because I can program and read IS29GL128/256 samples even though I got the following poor contact message.
"Please check whether the chip is good or their pins are inserting properly!
Programmer socket pin/s1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,23,24,34,35,36, HMI:1, HMI:2, HMI:3, HMI:4, HMI:5, HMI:6, HMI:7, HMI:8Chip pins is detected poor contact."
