As you say using the command srec_info I got:
Format: Motorola S-Record
Header: "epiphany-scrypt.srec"
Execution Start Address: 00000000
Data: 00000000 - 00000003
00000028 - 00000087
00000090 - 00001599
0000159C - 000015B3
000015B8 - 0000167F
8E000000 - 8E000695
8F000000 - 8F00057F
It means the core memory is used only up to the address 0000167F. That
means that I have around 27KB free. I guess that I can run TMTO 5 now or at
least I'm close.
Thank you Katja for your help it was really useful.
Regards,
Rafael.
