Hi!
I am trying to configure a new EMMC chip for installation in a TV, but I have a problem.
I can not write configuration bytes 162 177 179 EXT_CSD EMMC V5.1.
I read the section EXT_CSD as a programmer RT809H through a socket BGA153 and ISP.
Then I correct the dump in the WinHex editor, assign new values bytes 162, 177 and 179.
Then I write a new dump to EMMC, but the shell stops working, crashes.
When I read it again, I see byte 179 changing, but byte 177 and 162 do not change.
Is there any way to configure the new EMMC programmer RT809H?
If not, then will the algorithm be added to the program?

pimasında doğru. seçenek bastığımda otomatik isp bağlanmıyor. Okuma kalitesinde okur. Silme ile siler. Yazma ile yazmaz.
