Ivan,
I think you are close but not quite right.
Not checking the source, I think this is the original version:
> const SystemInitRecordData16NoAddress *r
> = (const SystemInitRecordData16NoAddress
> *)ra->init_records_data16_no_address;
>
> register volatile uint16_t *a = ra->init_record_address16;
> for (int i = 0; i < ra->init_record_number; i++) {
> *a = r->init_data16; // Write 16 bits
> a += 2; // Advance by 32 bits
> }
> }
I think there is here a very simple bug by me, r is not incremented while it
should be. Hence, it should be instead as follows:
> *a = (r++)->init_data16; // Write 16 bits and advance the source
> a += 2; // Advance destination by 32 bits
As far as I can see, that should work. Please test.
