Memo to me...

IDA free seems no ARM support...

Ghidra seems NSA supported... o_O

Maybe will spent some time with Radare2...

Not in next 5 minutes... but maybe in 2021. :alien:

Meanwhile will try to shrink TPK for my stupid tests...

18 files = 50 MB

shealth-measure is the Blood Oxygen part...

Will check if I can delete few of these files...

firstBlood_oldest_v4.tpk - shealth-service

Seems not impossible...

Best Regards
