07:53 <Guest53> I loaded a hex file to my TangNano9k external flash: openFPGALoader -b tangnano9k --external-flash numbers.bin

07:53 <Guest53> Following this the program stored in RAM was gone (also saw in the output the line "Erase SRAM DONE".

07:54 <Guest53> My question: is it possible to load a file to external flash w/o erasing the program in SRAM?

08:33 <trabucayre> Guest53: No

08:34 <trabucayre> You have to update your flash first and load bitstream into SRAM in a second time

08:34 <trabucayre> SRAM must be erased to be able to access flash

08:35 <Guest53> Thanks. As I can also load the "program" to internal flash (instead of SRAM) which is not touched by a subsequent load of "data" to external flash, it is not real a problem.

08:42 <trabucayre> Guest53: true

20:05 <Guest53> Just a question to upload speed to the Tang Nano external flash: I loaded a bigger file (600k) to the flash and it took more than 10 min to finish (did not time it exactly, but it was rather over 15 min). Is this the natural speed limit? Hopefully not ...
