Hello Vincent,
In Last november I tested Rlink to flash ST7263 MCU on our existing device.
I had some Problem because of our Reset design was not consistent with Rlink.
You said to me following :
...
Have you tried to remove only one of the capas? I think it should work. On our board, we put a 1uF capa with a 330Ohm pullup, and a 4.7K serial resistor. But the RLink is connected directly to the chip, not through the serial resistor.
See the REva and ST7263B daughterboard schematics for more information. You can also look at the ST board's
...
Could you please send me the detailed schematics of Reset ?
Also I have no more the CD of Reva + ST7263B daughterboard because I lost it when we moved to new building.
Should it be possible to have a new one pls ?
Thank's and Best regards
Jean-Luc

Hi,
You can find the schematic of the REva board in the RIDE documentation that is installed with RIDE. You want to look at the schematic of the motherboard AND the daughterboard. We don't have a "reduced" schematic, but for the reset it is quite simple:
The RLink is connected directly to the ST7.
The RC circuit (330Ohms/1uF) connected to the ST7 through 4.7KOhms serial resistor.
The push-button is in parallel with the capacity.
Concerning the CD, you can download the latest version of the software from our website there:

If you really need us to physically send you a CD, please send us your postal address by email.
Best Regards,
