[U-Boot-Users] cfi_flash init got real slow
by Reinhard Arlt 20 Mar '06

20 Mar '06

Hello, i have changed the flash support in u-boot for the CPCI750 from a local flash.c to the usage of cfi_flash.c a month ago. With the u-boot version from git from yesterday, flash init take about 20 seconds (it tooks no noticeable time with the last version). This is not acceptable. It is also not acceptable to disable flash protection. The problem is the code, that "invents" this "auto" flash unprotection in the flash_init routine. Please consider, that there are systems out with the env in eeprom, and, by the way, reading the "unlock" variable with the loop for each devive two times is not too good coding style. Please be carefull with changes, that have an impact to other systems. Kind regards Reinhard

[U-Boot-Users] IO serial problem
by Hurricane555 20 Mar '06

I´ve a NS9360 wich is similar to NS9750! U-Boot seems to boot. But I can´t make any input. When I type something in my hyperterminal the characters are not shown! I already checked the FIFO Register and the typed characters are in. Has anyone an idea!? The output has no problem! -- View this message in context: http://www.nabble.com/IO-serial-problem-t1297565.html#a3455063 Sent from the Uboot - Users forum at Nabble.com.

[U-Boot-Users] Patch for at91rm9200dk
by Andrew Zhukov 20 Mar '06

20 Mar '06

Description: Initial version of u-boot 1.1.4 uses Machine ID for at91rm9200. (The Machine ID is used by bootm coomand, while kernel loading.) The latest kernel 2.6.15.6 doesn't accept this Machine ID and won't load, for it expects ID for at91rm9200dk exactly. Note: Older kernels don't make difference and satisfied with generic at91rm9200 Machine ID. Correction (single line): Machine ID in /board/at91rm9200dk/at91rm9200dk.c is now exact ID of at91rm9200dk. Patch: See attachement

Hi, I am using 88E1111S PHY with TSEC1 on MPC8540The whole config for Ethernet config i used below mentioned.

[U-Boot-Users] SPI EEPROM on MBX problem
by Antonio Di Bacco 18 Mar '06

18 Mar '06

I'm trying to make a work an SPI EEPROM connected to the expansion connector of an old MBX board featuring MPC860EN processor. I used the spi.c driver in u-boot with no results, then I tried applying the patch from Gurevitch but nothing. Could I have problems with relocation of DPRAM for SPI? I double checked all the connections to the SPI EEPROM and it seems ok, when configuring the SPIMISO, SPIMOSI, SPICLK and SPISEL as GPIO active output I can measure a right voltage level on these pins when I write something to Port B data register. Unfortunately I have a not an oscilloscope to see what happen when I use the sspi command like this: sspi 0 8 05 (for Gurevitch patch) 05 is the code read a configuration register. Sometimes the EEPROM answer FF, some others 00 , it is completely randomic. Bye, Antonio.

[U-Boot-Users] SPI EEPROM problem on MBX (looping MISO and MOSI works)
by Antonio Di Bacco 18 Mar '06

18 Mar '06

I'm trying to make a work an SPI EEPROM (I tried with an AT25HP512 and an AT25256) connected to the expansion connector of an old MBX board featuring MPC860EN processor. I used the spi.c driver in u-boot patched from Gurevitch but nothing. Could I have problems with relocation of DPRAM for SPI? but I think this handled automatically. I simply defined CFG_SIMPLE_SPI_WRITE, CONFIG_SPI and CONFIG_SPI_X and it should be enough. I double checked all the connections to the SPI EEPROM and they seem ok, when configuring the SPIMISO, SPIMOSI, SPICLK and SPISEL as GPIO active output I can measure a right voltage level on these pins when I write something to Port B data register. Unfortunately I have a not an oscilloscope to see what happen when I use the sspi command like this: sspi 0 8 05 (with Gurevitch patch) 05 is the code to read a configuration register. Sometimes the EEPROM answer FF, some others 00 , it is completely randomic. I found that looping the SPIMISO and SPIMOSI with an external electric loop gives the right behaviour, I receive what I send. Anyone can help? Bye, Antonio.

[U-Boot-Users] Detailed documents......
by Mehul Gohel 18 Mar '06

18 Mar '06

Hi All, I am fresh engineer in this field working with DM6446 EVM DAVINCI board which contains DSP as well ARMEJ9. I need to bring that board up. I don't have any experience of how to load the boot loader, how the things goes after boot loader get loaded, so and so. I am working by reading all the document in u-boot source tree and going through the code of u-boot-1.1.3. So can anybody help me to provide document kind of material that gives step wise DETAIL of all the steps starting from boot loader installation to running kernel. such that it helps me to make my task ease. I am going to download the boot loader file through UART to internal RAM of ARM. Because I am confused that how to write the image in NAND FLASH, thats why I am using the other option and that is to download the boot image from UART where one host utility will be runing on the host PC that does few handshaking with board's primary boot loader and than downloads secondry boot loader from the host PC. Thanks, Mehul Gohel
