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.
