[U-Boot-Users] Flash Initializing problem, porting u-boot-1.1.3 on mpc850
hi, I am try to port u-boot-1.1.3 on a board with the processor MPC850. And i try to change the board of TQM850. It boots from flash on the board. I have successfully initialized clock, serial port (connect to RS232). The program can excute in flash and relocate to ram. But I got trouble on board/tqm8xx/flash.c flash_init(). The problem is finially located get_flash_size(), line 340-342. The 3 lines aim to get flash device ID. addr[0x0555] = 0x00AA00AA; addr[0x02AA] = 0x00550055; addr[0x0555] = 0x00900090; I change this code to fit my board: *(volatile unsigned short *) 0x02800aaa = (unsigned short) 0x00aa; *(volatile unsigned short *) 0x02800554 = (unsigned short) 0x0055; *(volatile unsigned short *) 0x02800aaa = (unsigned short) 0x0090; unsigned short ID; ID = *(unsigned short *) 0x0280; ( address connect as follows: mpc a[11..30] ==flash a[19..0], flash a19 mpc a11, flasha18 -mpc a12 ,.. notice LSB of mpc is a[30] not a[31], for flash is word mode. so the flash address 0x555, 0x2aa are corresponding the system address 0xaaa, 0x554 , left shift by 1 bit.) those 3 lines code have been tested on vxworks' bootrom on this board. Now , my trouble is : I cannot use printf to print number after executing the 3 line codes, like printf(Device ID is: %x\n,*(unsigned short *) 0x280); But it can print string , likes printf(Read Device ID\n). it seems just the second parameter cause the trouble. Sadly,this kind of printf can be used several times , then it stops. other kinds of function or instruction can be executed a little more, but stop finilly. I simply convert address to string ,then print. The result of ID is 0x0001, which is just the correct number. If I ignore the 3 line code above, the program runs ok except the initialization of flash. I really cann't figure out where the problem is. Could anyone help me , or give me some suggest! Below is the configuration on my board: oscillator 4MHz DRAM: 8M flash: AM29LV160DB (16 bit) IMMR.ISB = 0x0220 BR0 = 0x02800801 OR0 = 0xffe00936 Cross Compiler: GNU gcc 4.0.2 Result on hyper-terminal: CPU: XPC850xxZTB at 64 MHz: 2 kB I-Cache 1 kB D-Cache Board: ### No HW ID - assuming TQM8xxL DRAM: 8 MB Now running in RAM - U-Boot at: 007c1000 FLASH: ## Get flash bank 0 size @ 0x0280 BR0 : 2800801 OR0 : ffe00936 Thanks!

[U-Boot-Users] DTC and Binary Includes
Sascha(?) and/or others, I seem to recall that those working on the either the next U-Boot V2 or the next version of the FDT image structure were planning on using the binary include mechanism of the DTC. Several days ago I added the Binary Include patch to DTC and tagged a candidate release. Could you verify that this version satisfies your needs and works for you?

[U-Boot-Users] Does U-boot support ethernet chip LAN9210 from SMSC?
Hi, Does U-boot support ethernet chip LAN9210 from SMSC? If yes, how can I get driver source code? Best Regards. Seung Youl.- Check out the new SourceForge.net Marketplace.

Re: [U-Boot-Users] [PATCH][RFC] pci: Divided pci code of the powerpc
Hi, all. Could comment about this patch. Best regards, Nobuhiro Nobuhiro Iwamatsu wrote: A source code of pci is written mainly on powerpc. Macro uses a pci source code of powerpc because other architecture (ex. SuperH) doesn't work. I made asm-ppc/pci.h and moved macro of pci. Other archtecture need to make the following macro in asm-xxx/pci.h #define pci_phys_to_mem(dev, addr) (addr) #define pci_mem_to_phys(dev, addr) (addr) #define pci_phys_to_io(dev, addr) (addr) #define pci_io_to_phys(dev, addr) (addr) Or have to make a function for pci address conversion. However, I want comment because I do not know the other architecture. Signed-off-by: Nobuhiro Iwamatsu [EMAIL PROTECTED] - Check out the new SourceForge.net Marketplace.

Re: [U-Boot-Users] Does U-boot support ethernet chip LAN9210 from SMSC?
Hi Ben, Sorry for bothering you. I have downloaded the latest version of U-boot. There is smc911x.c file. I have added this file to Makefile. The compilation is successful. But, there are two problems. 1. there is no LAN9210 entry in chip id list 2. Only 32-bit is supported. Is there any recent driver for LAN9210? - Original Message - From: Ben Warren [EMAIL PROTECTED] To: 이승열 [EMAIL PROTECTED] Cc: u-boot-users@lists.sourceforge.net Sent: Monday, June 30, 2008 12:25 PM Subject: Re: [U-Boot-Users] Does U-boot support ethernet chip LAN9210 from SMSC?

[U-Boot-Users] CPU (405ep) clock upgrade..
Hi there, We've got a board powered by 405ep running at 266MHz. Now we want to upgrade the clock rate to 333MHz (model: 3LB333C), can anyone give us some pointers doing this? I've tried to search the mailing list but found nothing quite related. Also there seems to exist very limited ports, if not none, of this model to which I may reference. Below are questions that are more specific: 1. For CPU clock rate configuration, exactly what parameters should I modify? The suspected ones are FWDV (Feedback Divide) and FBDVB (Forward Divide B) which according to the processor user manual determines the PLLOUT A. 2. SDRAM clocking. I guess the clocking should be adapted to something like 111MHz (given the 333MHz CPU clock); however, the manual shows there there seems to be only two options, namely 100MHz and 133MHz. 3. Clocking of others such as PCI (on-chip PLB clock, sync/async PCI clock) and serial port. Are they supposed to be modified accordingly? 4. Any other parameters? Thank you very much for your guidance.

You don't have to add anything to the Makefile, just use the correct CONFIG options But, there are two problems. 1. there is no LAN9210 entry in chip id list So add it. I haven't looked at the LAN9210 data sheet to even know if it will work with this chip. You're going to have to do some work. 2. Only 32-bit is supported. Not true. Both 16 and 32 bit access is supported. Check the source code (hint: look for CONFIG_DRIVER_SMC911X_16_BIT) Is there any recent driver for LAN9210? I don't know of another or I would have told you about it. Good luck, Ben - Check out the new SourceForge.net Marketplace.
