TMS320C6746: Issues with sfh utility in Custom boards

Part Number: TMS320C6746
Other Parts Discussed in Thread: OMAP-L138, AM1808, AM1810, OMAPL138

Hi,

We are currently using a custom board which is having a C6746 DSP processor. We are having issues in using the SFH_OMAP-L138 utility. 

1. For a custom board re-compilation of the make file is required, so we have changed the device.mak file with the following strings :

#############################################################
# Device and Flash types for Makefile use #
#############################################################
#

# Generic string for device family
DEVSTRING=OMAP-L138

# Particular device types of the family
#ARM_DEVICETYPES:=OMAPL138 AM1808 AM1810 OMAPL138_LCDK
DSP_DEVICETYPES:=C6748
DEVICETYPES:=$(DSP_DEVICETYPES)

# Supported flash memory types for booting
FLASHTYPES:=SPI_MEM

2. We have also changed the device_spi.h and device_uart.h according to our requirement.

3. Whenever we try to write into the board, it is returning " Waiting for SFT on OMAP L138 "

4. What are thechanges required inorder to solve the issue?

Thank you in advance for any help you can provide.
