Hi !

Thank you for your help !

I've just tried your code and it works !

The flash details are good I think :

- Offset = 0 -> I don't know what that means

- region_size = 524,288 -> It's good

- numbre_of_blocks = 8 -> good too

- block_size = 65536 -> good

and :

num_epcs_regs = 1 -> I don't know what that means

I'm going to try to use the functions you've mentionned.

I need to translate a small part of an old code given to me by a teacher. He has used a component called "ASMI". I have read on internet that it's quite close to EPCS. Do you know how to translate functions like this one :

int nr_asmi_read_buffer (unsigned long address, int length, unsigned char *data); // This declaration is in escalibur.h

Thanks again for your useful help !
