|
|
Hello,
Does anyone tried to crack RR for 19nm MLC (EC DE A4 32) /TLC Samsung (EC DE 98 DE) NAND (registers 0xa7 ...... 0xa6) ??
We do some research work (extracted commands, registers and valuses) but still can't force FE by Debug commands to accept the set value to relevant registers.
All solutions on the market (FE, VNR and PC3000) using this same RR configuration for Samsung NAND and this RR working only with old 32nm chips (base 9 registers in VNR and PC3000 form 0xB1 to 0x12) and extra 3 registers available in FE. Also configuration of RR of those TLC NAND is totaly diffrent.
If someone have knowledge about samsung read retry please, contact with us maybe together we will make it work.
