Silicon TIM VME board status and service log

*TIM #54 and #55 require special TTC CLK selection by setting bit 8 of the TTC_Select (0x28) register. TIMs #50 and #56 aren't. Other TIM-3Fs to be checked.* most of TIM-3F's need FW from v0x5a for proper operation in TTC mode.* FFTV setup is based on two jumpers: SCT: PL203 unset and PL202 unset; PIX: PL203 set and PL202 unset; IBL: PL203 unset and PL202 set.

Firmware description can be found here. The XILINX iMPACT flashing software (as a part of the Lab Tools package) can be downloaded from here (it is free but registration is required). Beware of differences in L1A propagation delays w.r.t. backplane and TRO TIM ouptut for TIM3(C/F) flashed with firm v0x1e and 0x26 as has been measured by Matt.

Installation precautions in the populated ROD crate: as for the ROD, but pay especially attention to the capacitor on the left side of the TIM board. It sticks out of the board and if the TIM is pulled off the backplane by a few centimeters it may get in touch with the front panel of the ROD in slot 12 and get ripped off. So pull the TIM off the crate very slowly. The same precautions apply for plugging-in; in this case you can see the capactor isolated by a capton tape on the solder side of the board.

Here is the photo of the TIM, which lost its firmware (note all LA,CA,ER,BR,FR,SP LEDs are ON). If you see this you need to re-flash the TIM with the new firmware, with the revision you can find in the table above (valid for Pixel only, SCT to check!). To do so, pick-up the TIM flash kit (black laptop bag for PIX or white paper bag for SCT) from the IDCR room (on the open shelves on your left, contact Pixel or SCT on-call if in doubt), go down to USA 15. The TIM will be uncofigured, but it is better to have the ROD DAQ elements unconfigured in the data taking partition as a starting point. (For IBL ask Pixel on-call on the procedure, for old Pixel, you do not need to switch off optoboards since without TIM the BOCs will switch over to internal clock, however an optobord reset may be necessary after the TIM is back). Turn on the laptop, plug-in the cable one side to laptop USB port another side to the connector on the TIM front panel, start the script with the TIM frimware revision name in it (Pixel - from the desktop folder "TIM shortcut (visible for all)", SCT - directly from the desktop, follow the instructions on the screen. The healthy TIM after successful re-flashing should look like this. (For Pixel you can execute $ROD_DAQ/RodUtils/TimStatus script after logging in to the corresponding crate, which in case of healthy TIM will return its serial number, firmware and status information) If the re-flash wasn't successful you may try to re-flash the main TIM FPGA (FPGA1). An icon with the script (SCT) or a link from TIM shortcut folder (Pixel), flashing the FPGA1 with the firmware (v3) is provided. Then you could repeat the procedure above. If this won't work, replace the TIM.

In case the re-flash does not work or there is any other reason for TIM not to be configured, you need to replace the TIM. For Pixel, you need to pick up at the first place the TIM from the SR1 left (if you stay in front of the crates in the SR1 rack area) crate, also known as "crate 0". This is the only spare TIM3C card, other spares are TIM3Fs and need firmware revision equal and greater than 0x26 and a configuration code modification. Be very cautious (re-read the first paragraph in red above) dealing with TIM hardware! Do not forget to switch off the crate and the lasers on TTCex (using front panel switch on the module in the TTC crate with fibers coming out) before unplugging the fiber and use ESD protection.
