[U-Boot-Users] RE: PATCH: add low-boot configuration to MPC8260ADS family of boards (VanBaren, Gerald (AGRE))

Gerald, I think I have found some problem with the HRCW for lowboot in the MPC8272ADS board. In this board, IRQ5_, which is multiplexed via BAC with BADDR31, is used as PHY interrupt line. So BADDRxx are not being used at all and BAC=01, not 10 as it is in lowboot HRCW. I have not tested this, as my board's gone for some days, but at least, i think that for this board it should be HRCW=#0E74B646 instead of HRCW=#0EB4B645. I also include a log file from the BDI2000 where you can see that low bits in the flash are not accesible with this configuration (so that's why I think I can't get u-boot runnning). Could it be the same problem or another one? Best regards Alex

Hi, I plan to load u-boot to a sbc8260 board. There is no document available for this board. Any one has information about the pinout of the RJ45 as a serial port of this board? Thanks for your help.

JP13 pin 1 goes to a MAX3223 R1IN, pin 2 to T1OUT, pin 3 is unused, and pin 4 is ground. JP14 has the same wiring to the MAX2332 R2IN, T2OUT. gvb ****************************************** The following messages are brought to you by the Lawyers' League of IdioSpeak: ****************************************** The information contained in, or attached to, this e-mail, may contain confidential information and is intended solely for the use of the individual or entity to whom they are addressed and may be subject to legal privilege.

[U-Boot-Users] PATCH: add low-boot configuration to MPC8260ADS family of boards
by VanBaren, Gerald (AGRE) 08 Nov '04

08 Nov '04

Hi Wolfgang, Attached is a patch to allow the MPC8260FADS family of boards to be configured to boot either high (0xfff00000) or low (0x00000000). It was tested on a PQ2FADS-ZU (MPC8280 processor). I slipped in an unrelated change to the default load address and beg your indulgence in applying that as well. Thanks, gvb CHANGELOG: * Patch by Jerry Van Baren 08 Nov 2004 - Enhance the PQ2FADS board (aka. mpc8260ads) to boot high or low based on whether "lowboot" is in the configuration target name. If lowboot is selected, the jumper for the HRCW source should select flash. If lowboot is not selected, the jumper for the HRCW source should select the BCSR. The "boot low" configuration is highly recommended. With this configuration, the HRCW sets the IMMR to 0xf0000000 to be directly compatible with linux (the IMMR is properly positioned and does not need to be moved in start.S). - The patch also changes the default load base address to 0x00400000 (was 0x00100000) to allow linux to boot properly. ****************************************** The following messages are brought to you by the Lawyers' League of IdioSpeak: ****************************************** The information contained in, or attached to, this e-mail, may contain confidential information and is intended solely for the use of the individual or entity to whom they are addressed and may be subject to legal privilege.

Hi, I am working on PMC board which is based on MPC 8266. Can the existing PCI code in UBOOT be used for configuring the PCI in agent mode? Currently does any of the boards in uboot, are configured for PCI agent mode? Thanks a lot in advance.

[U-Boot-Users] GOT pointer in U-boot
by calvin 06 Nov '04

06 Nov '04

Hi, I understand that global pointer is adjusted with respect to end of u-boot data. But there is a reference to GLOBAL_OFFSET_TABLE in cpu/mips/start.S whose contents are assigned to "gp" in the code. My code does not have the memory location which gp points to ? How should I find out what should be the contents of gp ? README file does mention the use of global pointers but it does not have a reference to GOT pointer. Thanks and regards, Pooja

If production time is a matter for you (because you plan to produce a high number of boards), you could buy the flash chips pre-programmed. Or you could program the flashes _before_ soldering with an industrial flash programmer. Or you could use an in circuit tester (ICT) to program the flashes. For a smaller number of boards (0...1000 p. a.) a good JTAG Debugger like the BDI2000 is a practical solution. Regards, Martin
