dear,
Currently I'm trying to connect to a dcu3 target (stx5100JUib)
however I cannot get trap on.
I connected TRST but not RST (can this be an isuse?)
I already added the flash config for the device
this should be ST M28W160CB
http://pdf.datasheetcatalog.com/datashe ... s/7358.pdf
found a similar entry for this one and adapted the device id (just one hex character)
also I found the RAM chip to be the following HY5DU121622BT-J (512Mb)
http://pdf.datasheetcatalog.com/datashe ... zskrwy.pdf
what value should i used for this total in hex? What is the formula to convert Mbits to hex totals?
I added this to vender.xml
<Part>
<Name>STx5100</Name>
<Id>0xD423</Id>
</Part>
Probably the ram memory range is incorrect so the cpu can't be trapped? Do I need to connect the RST pin as well or is TRST sufficient? Can anyone find a datasheet fro STx5100? I can only find a brief product description
Maybe I need to find memory map to see at which address I should load the overlay?
Could you give me some assistance on this (maybe TeamViewer with usbbdm?)
thanks.

ok will try that address. Found one datasheet that mentions stx5100 as ST20 243Mhz. However no mentioning of DCU3.
when do you know a box is DCU3?

Will try to change register address. Maybe I can have more luck with st toolset..

I suppose it's juts st20. Using extremeview 3300 I get following response
-detect
IDCODE 2D423041
STi STx5100
Unknown flash type!
Report these values http://www.usbjtag.com/vbforum ffff,ffff
but no trap on. any idea why the flash query does show up? I thought this could only be done using trap on?
