AM1705 U-boot loading query

Other Parts Discussed in Thread: AM1705

Hi,

We are using AM1705 in one of our projects, and have following queries on u-boot downloading:
1) Kindly clarify through which interfaces can u-boot be downloaded on CPU or external SPI NOR Flash.
2) In my application, we are only going to provision for JTAG header on the board. We will not have emulation header or Embedded USB interface (as on OMAPL-137 eval board). Will I still be able to download and debug u-boot & application code through the JTAG header?
3) Can UART be used for downloading u-boot & application on CPU (my board will have limitations as mentioned in point 2).

Kindly revert back at the earliest.

Thanks & Regards,
Roma

    1) With the tools TI provides, the external SPI, NAND, and NOR flash can be programmed through UART boot with the serial flasher, or through CCS with the emulation flashing tools. U-boot can be converted to AIS format and booted directly from any of the AIS boot modes the device supports (NAND, NOR, SPI, UART, etc).

    2) Yes but you will require an emulator such as these: XDS510 XDS100v2

    3) Yes the device supports many boot modes including UART. By converting U-boot and your application to a single AIS image, you can load and boot directly via UART.
