Hi All, Wondering if we do have a collated lists of pending patches some place for the cfi_flash.c?

[U-Boot-Users] Locked block in StrataFlash
by llandre 30 Nov '05

30 Nov '05

Hi all, I experienced a problem with strataflash driver on ARM920T-based custom hardware. The driver has been derived from board/esd/cpcpi440/strataflash.c. When issuing a saveenv command, U-Boot randomly can't erase the block because it is locked (environment is in flash). We verified with JTAG debugger that status register and it confirmed the locked state. To unlock the block we issued manually the necessary commands. The function flash_real_protect is never invoked (I verified with JTAG debugger that it is never executed, too). Anybody experienced similar problems? -- llandre DAVE Electronics System House - R&D Department web: http://www.dave-tech.it email: r&d2(a)dave-tech.it

OK, my formulation was bad. According to the PCI specification this _should_ work. But there are PCI cards around with a 5 V key and a 3,3 V key (= combo-cards) wich drive 5 V on the PCI signals. Those cards are not compliant to the PCI spec, and could damage a 3,3 V only PCI board. On the IceCube board the signal levels on the PCI bus must not exceed 3,3 V, because the PCI pins of the MPC5200 are not 5 V tolerant. So it must be assured that a 3,3 V/5 V combo-card drives the PCI pins only with 3,3 V. Otherwis it _may_ work for a while (because the 5 V are shortend by the clamp diodes in the MPC5200 down to 3,3 V), but damage the board sooner or later. Regards, Martin

[U-Boot-Users] configure U-boot for ATI video card
by Bashier Machmur 30 Nov '05

30 Nov '05

Hello, I'm using on my custom board (PPC 440GX) an ATI M6-C16H Mobility Radeon video card. I work with U-boot and linux kernel 2.6.12 and installed the driver "radeonfb". Now I don't have the BIOS of ATI for PPC to support it. How can I configure the U-boot for ATI to initialize this video card? Thanks for any help, Bashier

If you had, what can be > done Is your PCI card a real 3,3 V card? The IceCube (Lite5200) board only supports 3,3 V cards. No 5,0 V cards and no 3,3 V/5 V mixed cards are allowed. Because of an unfurtunate design of the Lite5200 board it is possible to plug in a 5 V PCI card in reverse direction into the 3,3 V coded PCI receptacle. Regards, Martin

[U-Boot-Users] the irq of ARM926ejs in uboot
by terry 30 Nov '05

Hi, In U-BOOT, the irq of ARM926ejs was closed by a macro CONFIG_USE_IRQ. So the irq interrupt is no used, then how u-boot support the keyboard, network, and IDE hard disk, polling? if need support USB, can it still use polling driver? Thanks Terry

RE: [U-Boot-Users] tftp loadable applets?
by Zhen Wang 30 Nov '05

JD <davisjf(a)gmail.com> wrote: I noticed that there is a tftpboot command. Is there a similar mechanism in place for uploading applets via tftp? I had booted uClinux's compressed zImage utilizing 'tftpboot' command and a following 'go' command as my 'CONFIG_BOOTCOMMAND' successfully. Though I haven't tried to use 'tftpboot' to load applets, it seems possible in that zImage is also a binary file(not ELF). The 'CONFIG_BOOTCOMMAND' and some relevant configurations were configured as below in my include/configs/<board>.h: #define CFG_LOAD_ADDR 0x0c480000 #define CONFIG_BOOTFILE "zImage" #define CONFIG_BOOTCOMMAND "tftpboot\; go 0c480000" Note: 0x0c480000 is in the SDRAM address range.

[U-Boot-Users] U-boot suppoorts VPN?

I am working on a project. And I need to download the kernel from another board. Because there are more than switch between 2 CPUs, VPN is needed to make tftp work. Some guy told me that u-boot supports VPN, but need to do some configuration. I did read the README file, didn't find anything about VPN. Any ideas? comments?
