Hi members
I try many times to fix ext_csd fir example change value in file;:
179 to 00
167 to 0a
The emmc programming 100/100 with my ext_csd modify by me, or by repair ext csd.
I connect to the emmc to check if is the ext csd is ok, i see it is ok.
But if i start the product after disconnect the easy jtag plus, this product he can't work good and stop in logo.
I try to check the emmc by the easy jtag plus tool, but i see the ext_csd back to the old value before changing.
I try to programming the emmc with boot and rom1 and the ext csd all is ok, after disconnect the easy and check if the product work, this product can't work, use jtag plus secabd time to check, the value back to the old value (not changed after programing)???
Any one have a idea?

You can't need to manually edit this file
For change boot config you need use EasyJTAG software menu
