Burning new firmware in v1495

Following is an example of burning a firmware in the v1495 which is slave-2 of the v1495's in ccomptvme2.

• You need to login into the CPU of the crate which has this v1495 using telnet or minicom.

 telnet ccomptvme2

• change your directory to the place where you have the firmware saved

 cd "/home/cdaq/compton/firmware/"

• check if the list of files to confirm the new firmware in this location

 ls

• load the object file corresponding to the CAEN provided lib. [This library has the function 'v1495firmware' defined]

 ld < v1495.o

• check the VME bus address to which this v1495 is mapped. by running the sysBusToLocalAdrs command followed by printing the value.

 sysBusToLocalAdrs(0x39, 0x220000 , &laddr);
 printf("0x%x\n",laddr);

1st parameter: 0x39 stands for 24 bit addressing on my v1495 board, which could have been 0x09 in 32 bit addressing mode.

2nd parameter: 0x220000 is the hardware address set by me on the v1495-slave-2, by setting the Hexa decimal dip switches on the top of the board to '0','0','2','2'. the last 4 bytes are automatically '0'

slave-0 has a hardware address of 0x200000

slave-1 has a hardware address of 0x210000

slave-2 has a hardware address of 0x220000

slave-3 has a hardware address of 0x230000

3rd parameter: laddr is a local variable (stands for local address), (if it is not already defined, then enter "laddr =0" in the CPU terminal to create a variable with that name)

• finally run the function v1495firmware to burn in the binary file into the EEPROM of the v1495.

 v1495firmware(0xFA220000,"V1495CP_32bit_r320E.rbf",0,0)

1st parameter: 0xFA220000 is the local VME bus addr of the v1495, corresponding to my hardware addr of 0x220000, found in step 5

2nd parameter: V1495CP_32bit_r320E.rbf is the name of the (raw binary format) file that I want to burn into the User FPGA memory of the v1495.(in the local directory/folder where I call this function)

3rd parameter: 0 stands for writing in ['1' for reading out]

4th parameter: 0 stands for User FPGA ['1' for Bridge FPGA]

This will take around 5 minutes. wait until that time, after which I see a message:

 Updating firmware of the FPGA USER with the file V1495CP_32bit_r320E.rbf
 End of file: bp=112 bcnt=444952
 Firmware loaded successfully. Written 444952 bytes
 Reloading user FPGA firmware...done!

Reboot the crate once and the new code would be loaded.
