Tool/software:
The BQ34Z100 EVM does not respond to BQSTUDIO talking to it through an EV2400. The analog voltages on the BQ34Z100EVM look correct, with the incoming REGIN=4.0V, and REG25=2.5V.
It seems BQSTUDIO is assuming a different I2C address than expected by the BQ34Z100. On the I2C bus I see the bits 00001011010, which looks like the EVM is trying to write to address 0x0B, while the BQ34Z100 Reference Manual says "The 7-bit device address (ADDR) is the most significant 7 bits of the hex address and is fixed as 1010101. The 8-bit device address is therefore 0xAA or 0xAB for write or read, respectively." If that's the case, then that would explain why we see no ACK from the BQ34100Z.
I downloaded BQSTUDIO recently, and it's version 1.3.127.
What do I do next? How do I get the EVM to respond?
