ATF - how to change max number of retries? - GSM-Forum

Hi.

I have very unstable memory dump from Lumia 640.
I have downloaded 15% of full memory where ATF try to read the phone by 500 times. And ATF told me that:

I tried to find this kind of settings in INI file but I can't.

Is anybody could help me?

Thank you in advance.
Michal.

If you are using USB cable to get VCC/VCCq (QC) change it to stable power lab supply at 5.000V - we have seen many fluctuation in power that cause error on reading while using USB power from PC - you can check this with oscilloscope to see peeks and then see reaction with Retry in ATF immediately

Other solution is to periodically cut off USB power supply (using programmable power lab DC) for 5-10ms within every 20 minutes.. this can be programmed for example using Rigol DP832 - there was many old phones which it was only way to read using JEDEC JTAG

If this not helps you can split you can always split your reading into parts using address offsets (Start and End blocks) and then merge all into one file
