Putting Uboot back into H4 board

Hi,

I have an H4 board (OMAP-2420) with a broken Uboot. Can somebody point me at a set of instructions or a utility to replace it please?

Thanks,

Richard.

Hope you have got H4 Menelaus board. You can download h4 u-boot source from http://linux.omap.com and use OST tools, it is available from the ti site:

--------
Flashing Uboot (Menelaus Board)

Procedure for flashing u-boot using OST tools

1. Make the following switch settings

Menelaus SDR based board:

Processor Daughter card:

SW4: OFF, OFF, ON, ON
SW1: ON, OFF, ON, OFF(OFF, OFF, ON, ON for booting)
SW2: OFF, OFF, ON, ON(All ON for booting)
SW3: OFF, ON, ON, ON

Main H4 board:

S1: All ON except 1,2,9,10
S2: ON, OFF, OFF, ON

2. Connect the Serial cable to UART J400 socket (near to power supply) of H4 board and serial port of PC. NOTE: 1. Make sure that there is no other program running on PC monitoring the serial port.

2. DO NOT switch on the board just follow the instructions

3. Launch OSTtools tools Click on Settings->Configuration... menu to launch Configuration Dialog box In Configuration Dialog box

- Click on 'Restore Default Addresses' button
- Select '2420 Menelaus SDR' as platform
- Select 'UART' as interface
- Select 'FlashWriterNOR.out' file name as Flash loader
- select 'OST_Load.2nd' as Downloaded SW
- Click on 'OK' to close the dialog box

On main GUI window

- Select 'Image downloading and Flashing' as mode of operation
- Select 'h4_u-boot.raw' as input file name
- Click on 'Download To Target' button
You should see following message
'Waiting for Target to Send ASIC ID'

4. SWITCH ON the board. OST tools will download/flash the u-boot raw binary on to the board. OST tools will display the downloading/Flashing progress. The whole process will take less than 18 sec. Once the flashing is completed, close the OST tool and switch OFF the board

5. Make following changes and switch ON the board

SW1: OFF, OFF, ON, ON
SW2: All ON

NOTE: To get u-boot o/p you need to connect the serial cable to debug board
