Hello all,

We have updated the EE_demo code recently and it has been posed in 
the Files section of the forum. Revision 1.1 differs from the 
original one in the following:

- Flash erase and write routines now disable all interrupts before 
accessing the flash and enable them once they are done. If a 
specific application does not need this, lines of code providing 
this can simply be commented-out without affecting the routines 
themselves.
- Status feedback after a successful write in the Flash memory is 
fixed now. It the original release it used to report a mismatch even 
when it was not the case.
- Reading and counting records in a full EEPROM is fixed.
- Routine dedicated to finding out the next available location in 
EEPROM works with all combinations of Flash sectors now. The older 
release could handle an 8kB EEPROM but not a 12kB one; this is not 
the case any more.

We wish to thank everyone for the supplied feedback on the original 
code as well as the improvement suggestions. We are looking forward 
for your input in the future!

Regards

Philips Apps Team

Dear Philips Apps Team,

In the latest version of EE_demo.txt, you say:

"However, if sectors 1 and 3 are to be erased, it will take
one erase command for sector 1 (400 ms) and one erase command
for sector 3 (400 ms), totaling 800 ms."

The LPC flash architecture allows erasure of any combination of
sectors, not just consecutive sectors, in one 400 ms operation.

Why does the boot loader (IAP/ISP calls) not support this mode of
operation?

Kind regards,

Jaya
