AM1705 boot loader - supported SPI flash?

Other Parts Discussed in Thread: AM1705, OMAP-L137, AM1707

Hello,

1. Where I can obtain SPI flash devices list supported by AM1705 build-in bootloader?

2. Does bootloader support Atmel AT45DB321D-SU dataflash?

3. I have a small test UART debug output program linked to SDRAM.  If i want to run it on AM1705 (from spi flash)  i have to make a follow steps : 1. convert programm to AIS format by AISgen for D800K003 2.Flash AIS file to SPI flash by "OMAP-L137 UART Boot Host, Ver. 1.01". Can i use 

"

  TI Serial Flasher Host Program for OMAP-L137

  (C) 2010, Texas Instruments, Inc.

  Ver. 1.67

"

 for same purpose witch key : sfh_OMAP-L137.exe -flash_noubl -targetType AM1707 -v -p COM3 [my_program_AIS_format] ?

 

which best regards,

Arishchenko Ivan

    There is no list available. The ROM uses the defacto standard for Flash and EEPROMs and uses the read command 0x03, which is then followed by the address bits.

    A quick look at the datasheet shows that it should be.

    For flashing, this isn't quite right. The UART boot host tool is actually for booting the device via the host PC's serial port.  So you can create an AIS image by processing the .out executable with AISGen or HexAIS (the command-line utility).  The resulting AIS file could be booted to the device over the UART when the device is in UART boot mode.  Or the resulting AIS file could be flashed to the platform with the SFT command you showed (or it could be flashed by running a flashing program under CCS, as some directions for the platform indicate).

    I hope the above helps.
