I have the SB6121 with the flash chip MX25L6445EMI-10G and the Blackcat USB 1.8 board running in SPI mode with Enable JTAG VCC turned on, jumper set to 3.3v, and the BCUSB.3.01.SPI firmware. Pinouts connected as described in many places with Blackcat USB Pin 1 (3.3vcc) connected to the flash chip pin 2 for power. Those connections are clean and correct and I verified the 3.3v is supplied to the chip. The modem's own power is not applied. End result so far is that the flash is detected but not supported.
Is this a limitation of the jtag device as since it is not listed as a supported chip in the manual, or can the SPI be manually configured to access the flash? Hopefully I won't need to spend more $ on the NT unit.
Thanks for any help.
