 Hi,
I have VP-ISP10 with windows 10.(xp compatibility activated).tried idem with windows 7.
I try to use it by SPI on a Atmel AT24C16B (only, not other letter more)
I must use AT24C16(ISP) profile to have it recognized.
But for each operation,all fail with:
Device Address:00000000H　Device Data:00H
And i"m blocked to de-crash a bad bios update on an hp sr5707fr computer
What"s the problem please?
Thanks for the urgent help.

 1.check the ISP line, and make sure it connect well.
2.don"t connect chip VCC pin by ISP line,use PCB board power then try.
3.if both do not work, only check whether there are other devices around the chip circuit interference.

 see the Device Info.
A0　1 | 10
SDA 2 | 9　VCC
A1　3 | 8
A2　4 | 7　WP
VSS 5 | 6　SCL
link the right chip pin. and you need to know the position of the chip pin corresponding to the SPI on your board.
ex: if you SPI" GND connect the 24C16"s SDA,link it to pin 2.
by the way,AT24C16 use I2C protocol,not SPI. but you may try.

 Could the pegatron m2n78-la motherboard have a son8 bios chip instead of the atmel at24c16b chip that i see? supported by vp-isp10?

i don"t see really the correct one...

 vp-isp10 use standard I2C bus to program AT24C16B.
i donn"t know about SPI to I2C bridge. If it use the SPI protocol to write AT24C16,the programmer cannot write correctly.
if you only want to program AT24C16B,maybe you can take the chip down and link the chip pins directly.
