Hello, everyone,

We met with a problem about the connection between the chip and DAS. The chip we use is XC2224L, VQFN package. DAP connector of DAP miniwiggler. The schematic refers to the Easy Kit XC2XXX. The DAS can not recognize the chip. Memtool 4.4 was also tested but failed.

Already connect 'TDO_A' to 470R then GND and '/TRST' to 2.74K to +5V.

While connecting, 'RESET' is high. '/PORST' is high.

Do you have any idea about that?

Thanks.

Problem solved. It's something wrong with the Memtool settings for the chip XC2224L, and also some capacitors.

Do you mind to share the schematics ? I'm facing the same problem here but I can't find why I'm getting error.
