So... first post. I've been reading for a while and this forum is a great resource. I'm currently in the process on getting a car PC together and bench testing the software and hardware.
I have bought the Philips AE5010 Radio from Halfords at a cost of £19.99 and sure enough, inside was the Verona module. I have also built and tested a TTL level to RS232 level bi-directional converter using a max202.
From what I understand, the next step is to get some useful firmware onto the Verona to enable the Serial in/out ports. I'm at a bit of a loss as to where I acquire the firmware from . I will get onto building a parallel port programmer / buffer as soon as have a source for the firmware.
I have skipped through this thread from the beginning and have also done so with a similar thread on DC forum. Tying to extract the necessary information from nearly 4000 posts is a little tricky and I would very much appreciate any help anyone can offer.
Thanks in advance!

The pin function are dependent on the firmware, so you will need the right schematic for your radio.

True... but looking at the Frontier module description there is an analogue input that may just have the functionality I would like to exploit already!

I'm having trouble flashing the Verona with sermmi fw, well I'm having trouble dumping the original fw to be more accurate.
Should the software auto detect the flash chip?
When I dump the fw all seems to go fine but when I attempt to verify the dump it fails on the first byte.
Any advice other than check the soldering?

The flash chip should be auto detected by the SW, if its not detected then theres something wrong.
The RESET pin of the DAB module should be connected to 0V so the module does not try to bootup.
and the RESET from the programmer should be connected to the CS of the DAB module as stated on Adam's site >
WARNING: In case of programming Atmel DataFlash memories, RESET signal defined in pinout must be connected with ChipSelect (/CS) line of the chip.

That's possibly what I'm doing wrong then, I have cs and both reset's grounded.

The CS# pin of the Flash memory should be controlled by the programmer, as this triggers some internal processes of the memory.
To check your setup, read the flash memory before attempting anything else. Then open the file with an hexadecimal editor and check for some ASCII strings, like the version. If you have used the radio before, you will also see the list of most recent station names, frequency...appear in the dump.

If anyone is after a Verona module, just to let you know Tesco are still selling the Technika 1101ST on Ebay, item no.270828782975 for £11.49.
They have sold a LOT, don't know how many they really have left!
Woah! Just seen my email notifying me that ibf has posted the Tesco deal, spooky! Anyway here's a picture....
Did finally manage to flash a Verona with the serial MMI firmware and knock up a quick C# program to control it.

The 2 links to Tesco are from the raspberrypi forum, LOL small world indeed. TS is one of the member in here I bet.
Anyway, Tesco have been selling that same radio for many months now. Some of their shop might still sell it. I got it when it was still priced at £19.99 on the shelf, they charged me £9 when I got to the counter.
You might wanna include a character converter so that the RDS/radio text/DLS... are displayed properly on the PC.
