[U-Boot-Users] Board HW ID
Hello,
I've put a re-compiled u-boot on a tqm823 module. This wiped over the serial number and ethernet MAC address on the module. Re-setting the ethaddr is no problem as it is printed on the back of the module.
I imagine I can do likewise for the serial number.
What about HW ID? Here is part of the u-boot boot-up message:
CPU: PPC823EZTnnB2 at 50 MHz: 16 kB I-Cache 8 kB D-Cache Board: ### No HW ID - assuming TQM8xxL
I would like to set u-boot/include/configs/TQM823L_myversion.h such that the Hardware ID gets set correctly. Can anyone tell me how?
Many thanks
Seb James.

ethaddr is no problem as it is printed on the back of the module.
And so is (most of) the board type code, serial number, number of assigned MAC addresses.
I imagine I can do likewise for the serial number.
Not exactly. Some parts (like internal revision code) are NOT printed on the module.

Send me a message containing the MAC address (or serial number, or just the date when you bought the module) and I can look it up in our database.

And these are found in flash, start address 0x1ffc0, I think.
I followed the instructions from the ppcboot howto on the denx website:
----------------------- To install a new PPCBoot image on your TQM8xxL board using a BDI2000, proceed as follows:

However, the rm der 0x200xxxxx lines produced an error.
What do the rm der 0x2002000f and rm der 0x2006000f lines do?
rm modifies a general purpose/user defined register, but there is no register with the name DER or der in the tqm8xxL.cnf file; though if you look the init section of tqm8xxL.cnf:
[INIT] ; init core register WREG MSR 0x00001002 ;MSR : ME,RI WSPR 27 0x00001002 ;SRR1 : ME,RI WSPR 149 0x2002000F ;DER : set debug enable register ;;WSPR 149 0x2006000F ;DER : enable SYSIE for BDI flash progr.
DER seems to be the debug enable register. Seems like the plan is to set some sort of system interrupt enable before erasing the flash with u-(ppc)boot on, after when the system is put back into debug enable. However, it doesn't work on my BDI.
I would like to set u-boot/include/configs/TQM823L_myversion.h such that the Hardware ID gets set correctly. Can anyone tell me how?

Right.
I followed the instructions from the ppcboot howto on the denx website:
It seems you did so only partially.

So the commands you need are:

However, the rm der 0x200xxxxx lines produced an error.
You can ignore this error.
What do the rm der 0x2002000f and rm der 0x2006000f lines do?
Clearing/setting the SYSIE bit in the DER. The fast flash routines used by the BDI2000 use system calls, so these should not be trapped. This is probably no longer necessary with recent versions of the BDI2000 firmware.
rm modifies a general purpose/user defined register, but there is no register with the name DER or der in the tqm8xxL.cnf file; though if you look the init section of tqm8xxL.cnf:
Your BDI2000 config file probably includes a register definitions file "reg860.def" or so. This should contain lines like these:
... xer SPR 1 lr SPR 8 ctr SPR 9 dec SPR 22 pc SPR 26 ; is SRR0 srr1 SPR 27 eie SPR 80 eid SPR 81 der SPR 149 ictrl SPR 158 sprg0 SPR 272 sprg1 SPR 273 sprg2 SPR 274 sprg3 SPR 275 immr SPR 638 ...
This is where the definition of DER is coming from...
DER seems to be the debug enable register. Seems like the plan is to set some sort of system interrupt enable before erasing the flash with u-(ppc)boot on, after when the system is put back into debug enable. However, it doesn't work on my BDI.
Missing / broken / old version of reg860.def ?

Right.
I followed the instructions from the ppcboot howto on the denx website:
It seems you did so only partially.
This is the section, from http://www.denx.de/e/doc/TQM8xxL/ppcboot.php which I didn't read:
----------------------------------- 4.5.1.2. Board Identification Data All TQM8xxL boards use a serial number for identification purposes. Also, all boards have at least one ethernet (MAC) address assigned. You may lose your warranty on the board if this data gets lost. Before installing PPCBoot or otherwise changing the software configuration of a board (like erasing some flash memory) you should make sure that you have all necessary information about such data. -----------------------------------
Followed by this one, which is a long way down from the 'loading ppcboot using bdi2000' section:
----------------------------------- 4.9. The First Power-On Tip: Note: If you bought your TQM8xxL board with PPCBoot already installed you can skip this section since the manufacturer probably has already performed these steps.
Connect the port labeled COM.1 (X.18) on your TQM8xxL board to the designated serial port of your host, start the terminal program, and connect the power supply of your TQM8xxL board. You should see messages like this:
Connecting to /dev/ttyS1, speed 115200. The escape character is Ctrl-\ (ASCII 28, FS) Type the escape character followed by C to get back, or followed by ? to see other options. ----------------------------------------------------
PPCBoot 1.1.5 (Mar 21 2002 - 19:55:04)
CPU: XPC860xxZPnnD3 at 50 MHz: 16 kB I-Cache 8 kB D-Cache FEC present Board: TQM860LDDBA3-P50.203 DRAM: 64 MB FLASH: 8 MB In: serial Out: serial Err: serial PCMCIA: No Card found
Type "run flash_nfs" to mount root filesystem over NFS
Hit any key to stop autoboot: 0 =>
You can interrupt the "Count-Down" by pressing any key. If you don't you will probably see some (harmless) error messages because the system has not been initialized yet.
At first you have to enter the serial number and the ethernet address of your board. Pay special attention here since these parameters are write protected and cannot be changed once saved (usually this is done by the manufacturer of the board). To enter the data you have to use the PPCBoot command setenv, followed by the variable name and the data, all separated by white space (blank and/or TAB characters). Use the variable name serial# for the board ID and/or serial number, and ethaddr for the ethernet address, for instance:
=> setenv serial# TQM860LDB0A3-P.200 10061684 4
=> setenv ethaddr 00:D0:93:00:05:B5
Use the printenv command to verify that you have entered the correct values:
=> printenv serial# ethaddr serial#=TQM860LDDBA3-P50.203 10226122 4 ethaddr=00:D0:93:00:28:81 => -----------------------------------
