Storing data on the GP memory
dogusural opened this issue · comments
Hello , I am trying to use the chip for secure data storage but writing to some OIDs directly doesn't
work as expected. I can write & read what I wrote to memory regions between F1D0- F1DF by
using optiga_util_write_data and optiga_util_read_data. Although the functions return
OPTIGA_LIB_SUCCESS , I cant seem to read what I wrote to OIDS F1E0, F1E2 and E0E8. I
believe I will have to set up the meta data for these regions before I can put my persistent data
there. The page under the wiki didn't really help me much . How can I set the OIDS so that I can
write & read to them and the data stays there until I overwrite and can be modified anytime ?
I have been reading the Wiki and the solution reference manual since yesterday evening and honestly I have no idea how to set the GP memory for simple read / write operations. Can you please help me ?
F1E0 and E0E8 are working on my end. F1E2 is not a valid object ID.
Seems like the your problem is solved?
Yes I figured F1E2 wouldnt be a valid location to write, can you show me where it is mentioned that that object is not valid ? Because on the wiki it says General Purpose Data 2.
