Working project

Post by usbbdm »

I am working on adding SD card read/write support for USB JTAG NT. This is for future on board NAND support.

After study the protocol, I think there is a hardware limitation to access SD card with USB JTAG NT. There is a need to use slow clock to get SD card into SPI mode while the slowest clock for NT is 3MHz.
However this does not prevent USB JTAG NT to support NAND flash via SPI if target supports it. Like our support XBOX360.
So I might need to skip the support SD card and directly go to NAND via SPI when I have enough info to get started.

Another fun project will be allow USBJTAG NT to go into programming mode.
That is use one USB JTAG NT software with several USB JTAG NT with its own control to program the target.
I will keep you posted about the experiment.
