Part Number:AM1705
Tool/software: Linux
Hi,
We are using AM1705 with SPI flash as SPI boot and XDS100V2 for programming.
We are referring the below mentioned steps for installation process.
The project was already completed long ago and it was working fine. Now we have a requirement for some new additional features. Unfortunately, the no one from the team who had worked on this earlier is available now. The new team is trying to make the changes, but getting stuck while installing same u-boot.
We are able to download the uboot as per the steps below, but there is no console output at any uart for further kernel installation.

At what uart there will be console output for uboot?
Procedure to burn ARM UBL & U-boot in SPI Flash
ARM UBL & U-Boot are programmed using CCSv4. The following given screenshots gives ARM UBL & UBOOT programming in detail.

Procedure to burn Ramdisk & kernel in SPI Flash
To flash Ramdisk & kernel in SPI Flash follow the procedure given below:
For flashing Ramdisk & kernel in SPI Flash we use U-Boot. U-Boot SPI flash read/write commands are used to burn Ramdisk & kernel in SPI flash.
To stop the automatic booting (autoboot) of the pre-installed kernel, send a character to the serial port by pressing a key from the serial console connected to the target. If U-Boot is stopped, it displays a command line console as given below.

Now enter following SPI command to initialize the SPI device connected to EEPROM
U-Boot> sf probe 0
Now enter the following command to copy Linux kernel image into the RAM of the system
tftp 0xc0700000 uImage
Now Linux kernel image is stored in RAM at location “0xc0700000”. Now store the Linux kernel in SPI flash at location “0x60000”. Enter the following commands to erase & Write kernel image in SPI Flash.
U-Boot> sf erase 0x60000 0x300000. This command erases the“0x300000”contents of SPI flash from location “0x60000”.
U-Boot> sf write 0xc0700000 0x60000 0x300000. This command writes“0x300000”amount of ram contents in SPI flash starting from location “0x60000”.
Now follow similar procedure for writing Ramdisk contents in SPI Flash.
Enter the following command to copy Ramdisk image into the RAM of the system
tftp 0xc1180000 ramdisk.gz
Now Ramdisk image is stored in RAM at location “0xc1180000”. Now store the Ramdisk in SPI flash at location “0x60000”. Enter the following commands to erase & Write Ramdisk image in SPI Flash.
U-Boot> sf erase 0x400000 0x400000. This command erases the “0x400000”contents of SPI flash from location “0x400000”.
U-Boot> sf erase 0x400000 0x430000. This command erases the “0x400000”contents of SPI flash from location “0x430000”.
U-Boot> sf erase 0x400000 0x440000. This command erases the “0x400000”contents of SPI flash from location “0x440000”.
U-Boot> sf write 0xc1180000 0x400000 0x400000. This command writes“0x400000”amount of ram contents in SPI flash starting from location “0x400000”.
U-Boot> sf write 0xc1180000 0x400000 0x420000. This command writes“0x400000”amount of ram contents in SPI flash starting from location “0x400000”.
U-Boot> sf write 0xc1180000 0x400000 0x440000. This command writes“0x400000”amount of ram contents in SPI flash starting from location “0x400000”.

Please help since we are stuck and our project schedule has got delayed.
Thank you,
