2008-05-16 00:27:09 external peripheral access problem in BF561
Praveen Deshpande (INDIA)
iam accessing external peripheral from BF561 using asynchronous memory bank 1
The following setting has being made to access the device.
EBIU_AMGCTL ---- Enable all banks
EBIU_AMBCTL0 ---- 0xFFC2
still we are not able to access the device registers.
what could be the problem? Can anybody suggest.
and one more problem is while allocating memory for the data structures of the peripheral, we get following error
-------- HARDWARE ERROR -------
External memory addressing error

you've showed the settings for Bank 0, not Bank 1
you should start slow and verify that the hardware actually works ... when you try to read the address you think the device is on, the request actually goes out to the device
as for hardware errors, that shouldnt occur when calling malloc ... either things are severly corrupted by another process, or your hardware is flaky
