EMMC在线读写需要找到VCC/GND/CLK/CMD/D0至少5根线。VCC/GND这个最好找，不用多讲。
如果有图纸或者拆了EM ...

Hello

today encountered a problem, cannot write dump larger than 4GB on emmc, tried several emmc chips, all same result. Everything gets written up to 4GB, after that program just loops at 52% or 53% depends on chip size. When i verfy what is written it is only 4GB. Only way to write whole chip is to use "options" and to limit from 0-3500MB then from 3500-7500MB writing from two parts, but then i get currupted at least one sector and i have to repair it manually. I persume this is problem of using 32-bit integer in program code instead of 64-bit (long) integer. Can this be fixed with patch as is really unusable like this.

Thanks.

i love you

there is another error now, can you please check, i write file SDA.img it writes it but also reports an error about missing file SDA.img.part1  (line 46) which i never had as my dump is only from one part called SDA.img

is this OK ?

jbosko

Also, please, when i read chip, i get dump in two files one is name as i wanted, second is called .part1, i need to merge these files to get original dump ? And for writing dump, i need to cut file on some exact size as it asks for .part1 even if not exists and first file is 7.5GB ? Or we can use only dumps made by RT809H software ? This would be really bad.
