LMIFLASH and JTAG
CorrecT me if I am WRONG : -
Eric,
1) LMIFLASH utility implements a JTAG programmer via a FTDI's FT232 driver chip and hence it is non compatible to Wiggler hardware.
2) And if we do not want to buy Luminary Development board, can we DIY our own FDTI FT232 chip board programmer and make our own and just use the LMIFLASH utility ?
3) If LMIFLASH utility does not require firmware
sitting inside the LM3S102 chip or there is No seriaL number sitting inside the CAT93C46 chip that requres authentification, we can readily do it, right or wrong ?

Answers:
1. Yes, LMIFLASH uses FTDI's D2XX drivers to communicate with the FT2232, and is not compatible with any other hardware.
2. Yes, you can definitely implement your own FT2232 interface and use LMIFLASH. The only thing other requirement (other than the FTDI chip) is that the USB EEPROM be programmed with something that LMIFLASH knows about, meaning that the device string would need to be named as one of our boards. If the requirement arises, I can change the utility to allow you to pass a device name for connection purposes.
3. This kind of ties in with (2). The current implementation of LMIFLASH requires that the board be one of the device name strings that we program into the EEPROM at the factory. Those names are:
"LM3S811 Evaluation Board A"
"LM3Sxxx Development Board A"
"USB <-> JTAG/SWD A" |
