How to Program DTC Flash

1. Log on to CMS1 as user daq (usual password, Mega....).

2. Copy the MCH file generated by Xilinx to somewhere on cms1. You can for example grab it from Wu's download area directly with a command like this:

  $ wget http://physics.bu.edu/~wusx/download/DTC/DTC_test.mcs

3. Convert the MCH file to binary with command like this:

  $ srec_cat DTC_test.mcs  -Guess -Output DTC_test.bin -Binary

4. Copy the binary file to the directory /tftpboot/mch like this:

  $ cp DTC_test.bin /tftpboot/mch/

5. Make sure the USB and Ethernet cables are connected. Power up the MCH. Connect to bul3x1 with remote desktop (log in as daq). Launch putty.exe from desktop. Click on 'USB for MCH COM4' and 'Open'. If this gives an error, try again with 'USB for MCH COM3'. Then hit "Enter" and you should get the "nat>" prompt, and you can type commands.

Type the following commands:

  nat> diag
   ...
  DIAG (RET=0/0x0): 9
   ...
  CLK (RET=0/0x0): 1
   ...
  SPIFL (RET=0/0x0): 7

After this you should cycle the power to reload the FPGA from the new flash image.
