[U-Boot-Users] wlan driver
by Dan Malek 01 May '05

01 May '05

Hello everyone. Has anyone worked on a 802.11 wireless driver for u-boot? I'm faced with a board that has mini-PCI, adapters aren't working for standard cards, and it looks like the only solution may be a 3.3V wireless LAN card. There are some "standard" 3.3V mini-PCI cards for laptops, but I don't know how the connectors attach or if the magnetics are on the cards. If anyone knows, that would be useful information too. Thanks for any suggestions (I suspect Wolfgang will respond with a URL to an archive I couldn't find) :-) -- Dan

Re: [U-Boot-Users] PPC: How to access RAM location 0x0 (unmapped) ?
by KokHow Teh 28 Apr '05

28 Apr '05

The reason of the crash was because I put get_ram_size() before the sdram controller was initialized. I don't know how it works in sbc8240 but this is what I get in tqm8260: /* We must be able to test a location outsize the maximum legal size * to find out THAT we are outside; but this address still has to be * mapped by the controller. That means, that the initial mapping has * to be (at least) twice as large as the maximum expected size. */ Now it works. Thanks.

[U-Boot-Users] Write buffer programming for AMD flash chips
by Thomas Schäfer 28 Apr '05

28 Apr '05

Hi Alex, I had a look at your patch and I believe that it does almost the same than mine. From a point of readability and extendability I would prefer it, whereas my patch would save some memory. A missing part in your patch is checking whether data to be written are aligned with the flash chips write buffer. This is done with the following hunk for the write_buff function: buffered_size = (info->portwidth / info->chipwidth); buffered_size *= info->buffer_size; while (cnt >= info->portwidth) { - i = buffered_size > cnt ? cnt : buffered_size; + /* write buffer until next buffered_size aligned boundary */ + i = buffered_size - (wp % buffered_size); + if (i>cnt) + i = cnt; if ((rc = flash_write_cfibuffer (info, wp, src, i)) != ERR_OK) return rc; i -= (i % info->portwidth); In our case, the lack of this code lead to errors when writing the environment to flash. The reason is that environment writing is done in 3 steps and this results in not buffer-aligned write cycles. The code above calculates the correct buffer size (i) depending on the first address (wp) to be written Best regards, Thomas Schäfer E-mail: thomas.schaefer(a)kontron.com

[U-Boot-Users] resetting compact flash card in u-boot
by Tom Otermans 27 Apr '05

27 Apr '05

Hello List, I have a question about resetting compact flash cards. We are currently working on an pxa-255 system. From u-boot (1.0.0) a kernel image is loaded (on a fat partition) and booted. The problem starts after reading this image. The linux kernel (2.4.26) is started and tries to couple the root filesystem from the cf (parition 2, ext2). With industrial grade cf cards from sandisk, this process works fine, but non industrial grade cards can't read the data from the cf. If I do an ide reset, and load the image from the device via the fatload command, _remove_ the cf and than bootm the image, the cf card can be read in the kernel. So reseting the cf card somehow is what I have to do. Thus I tried to reset it by lowering the reset pin of the cf (lower pin 41 in true ide mode). But the problem still appears. Does anyone had these same problems with non industrial grade cf cards? Or any idea of how to reset the card in the bootloader to a same state as from inserting the card? Thanks in advance, Tom --

[U-Boot-Users] Baudrate of UART in U-Boot
by andreas_schmidt＠ifm-electronic.com 27 Apr '05

27 Apr '05

Hallo at all I'm jaust porting the u-boot at memec Board. After I adjust some thing(from ML300 Board), then compile u-boot and download it tn SDRAM. Now my Problem: At Hyperterminal a can only see that the blang blink not regulary and so a signal is on RS232. Than I measure the Baudrate with oszi and compare it with standalone application from XILINX EDK. The Signal from U-Boot UART differs on factor 1000 to signal from standalone application on RS232. Then i treid to change the Baudrate in U-Boot. I modifay the CFG_Baudrate ml300.h then i tried modifay it in xparameters.h but nothing have happens. Can me somebody say how I modifay the Baudrate in u-boot? thanks best regards, Andreas Schmidt

> Thisis only to be expected.

[U-Boot-Users] struct NS16550 {...} __attribute__ ((packed)) at ns16550.h
by Woojung.Huh＠smsc.com 26 Apr '05

26 Apr '05

Hi All, I'm newbie to u-boot. We are using u-boot for proprietary ARM board with NS16550 compatible serial controller. It is configured as 4bytes access to serial controller, so set CFG_NS16550_REG_SIZE to 4. But, because of "__attribute__ ((packed))" of struct NS16550, all register accesses to NS16550 are generated to byte access (LDRB, STRB in ARM). I think it should NOT have __attribute__ ((packed)) if NS16550 is configured as 4bytes access. Am I missed something? Thanks, Woojung

hi all, I have enabled a redundant environment and my two environments reside in two different sectors in flash. Everything works perfectly, except seems there is a problem in saveenv command: in file common/env_flash.c line 205: if ((rc = flash_write(env_ptr->data, (ulong)&(flash_addr_new->data), sizeof(env_ptr->data))) || (rc = flash_write((char *)&(env_ptr-crc), (ulong)&(flash_addr_new->crc), sizeof(env_ptr->crc))) || (rc = flash_write(&flag, (ulong)&(flash_addr->flags), sizeof(flash_addr->flags))) || (rc = flash_write(&new_flag, (ulong)&(flash_addr_new->flags), sizeof(flash_addr_new->flags)))) it writes a char to (ulong)&(flash_addr->flags), but this sector was never erased. am i missing something here? flash is STM M29W040, connected with 8 bit bus. Thanks, Ara

[U-Boot-Users] U-boot 1.1.2 on SMDK2410

Hi, We attempting to bring u-boot 1.1.2 up on a SMDK2410 board and are having a few problems. I have search through the mailing list and googled the net for some information but was not able to find. I build u-boot 1.1.2 as the following make smdk2410_config make I am using gcc 3.3.2 and the build went through without any errors. Using a ARM RealView ICE, I downloaded the resulting u-boot.bin to address 0x33F80000. Set the PC at 0x33F8000, and start the code execution. I was hoping that the serial port would come alive but nothing came out. No signs of life was showing from the board. I have configured smdk2410 to non-NAND boot. All the other configuration are left as default. Any advice on which areas to look at or any suggestions would be greatly appreciated. Many thanks, Tehn Yit Chin Software Engineer, Grey Innovation Pty. Ltd.

Thomas, What about the patch I have submitted some days ago? I proposed there some changes for the same issue? Have you considered/tested it against your Flash?
