i just solder the 6pin jumper wires included on the package and solder floppy cable wire length 10cm directly to the chips then the flash is detected
ok ill try to shorten the length of cable and post the results thanks for the advice
@jhaye: I have just tested a Spansion S25FL128P device with BCUSB (build 304 / SPI FW 1.09), the SOIC-16 package using the SPI socket adapter and it reads and programs 100% correctly. The write speed is around 160KB/s.
Therefore, I would assume your connection is not setup correctly. On the PCB board, you need to have 3.3v jumper on, and for the wiring, you should make sure VCC from BCUSB Pin 2 is connected to both HOLD# (pin 1) and VCC (pin2).
In addition, also make sure your GROUND (BCUSB pin1) is properly connected to the package.
You dont necessarily need the adapter , however it does make the job a lot easier if you have lifted the chip.
Could you perhaps post a picture of how the device is connected so we have a better idea of any underlying issues .
demon tell me if i am wrong but if i remember correctly, you can skip the vcc connection to the board if you power the modem from its factory power supply. just plug it in and have all of your chip pins connected correctly.
im using pcb1.8 i follow all diagram and the chips identify correctyl and jedec id is correct thats no problem on wiring etc...
it works now what i do is let blackcat read the flash then it became ffffff or blank it means programming by automatic it will erase the the whole flash chips this im wondering why
then do a manual configuration see the pictures posted above got correct id then do flashing after finish writing by manual configuration try to read using blackat automatics settings and manual setting then do compare to the source
ill use 3.3v and ground from bcusb directly solder to chips
Ok so on build 282 with firmware 1.09 it reas and writes 100%
With build 282 with firmware 2.02 it does not detect the flash ?
with build 321 with firmware 2.02 it does not detect the flash ?
With build 321 with firmware 3.01 it detects the flash but does not write ?
