Fix TRAB channel switching delay for trab_fkt.bin standalone applikation Patch by Martin Krause, 08 Nov 2005 In tsc2000_read_channel() the delay after setting the multiplexer to a temperature channel is increased from 1,5 ms to 10 ms. This is to allow the multiplexer inputs to stabilize after huge steps of the input signal level.

hi wd, I think I hadn't explained my situation clearly in my last post. I did copy board/pleb2/flash.c as my board's flash.c because this file provided flash driver for Intel 28F320C3B flash memory and created a configuration header file for my board. I don't know whether this could be called 'adapt the flash driver' but in the end I could see u-boot's output in minicom and the flash memory was correctly recognized. Now the problem is that 'erase' command doesn't work, I do need some precious hints about how to solve it. Besides, I wonder if cfi_flash.c can drive Intel 28F320C3B on my board because there is no CFI on my board.

[U-Boot-Users] Lite5200B support on U-Boot.
by Txema Lopez 08 Nov '05

08 Nov '05

Hi all, In a couple of weeks we will recieve a Lite5200B for evaluation. Looking into the Lite5200B User Manual we have found that the board comes pre-loaded with a U-Boot version. Does anyone know if this U-Boot version source code is now available? Will it be?. Has the low-boot been ported to that board? We have found nothing about it in the U-Boot repository (searching for Lite5200B, we don't know if the board is known by other name). TIA, José María López,

[U-Boot-Users] AMCC Yellowstone board update
by Steven Blakeslee 08 Nov '05

08 Nov '05

Attached is a patch to update the support for the AMCC Yellowstone board. It does the following. 1. Enable the PCI interrupt. I submitted a patch previously that did this same thing. 2. Disable the FLASH write protect in the board control and status registers. 3. Added a function to dynamically figure a value for the SDRAM0_TR1[RDCT]. This value needs to be adjusted on each boot and any 440 designs with DDR should do this.

[U-Boot-Users] MPC83xx PCI support - TQM834x patch?
by David Updegraff 08 Nov '05

08 Nov '05

Kumar, et.al. ..and there is also this errata still in processor Revs. 1.0, 1.1 MPC8349ECE.pdf, see Errata PCI6. "Pci host configuration read from unused slot terminates with CSB error" To my understanding, this errata prohibits speculative scanning of the PCI bus. So that you must only query slots/devid's you know ahead of time are valid.. Right? -dbu.

[U-Boot-Users] Problem in Passing MAC address from u-boot to linux after reading it from eeprom
by Vijay 08 Nov '05

08 Nov '05

Hello All, I am working on u-boot-1.1.2 and working on MPC8540 based board.I have one issue regarding reading MAC address from EEPROM and passing the same to Linux. I added little bit of code in common/main.c to read mac address from eeprom as follows. printf("\n Reading EEPROM for MAC addresses"); if(i2c_read(0x50, 0, 1, macbuf, 12) != 0) puts ("Error reading EEPROM chip for MAC address.\n"); udelay(100); sprintf(macaddr1,"%02X:%02X:%02X:%02X:%02X:%02X\n",macbuf[0],macbuf[1],macbuf[2],macbuf[3],macbuf[4],macbuf[5]); sprintf(macaddr2,"%02X:%02X:%02X:%02X:%02X:%02X\n",macbuf[6],macbuf[7],macbuf[8],macbuf[9],macbuf[10],macbuf[11]); printf("\n%s",macaddr1); printf("%s",macaddr2); eth_set_enetaddr(0,macaddr1); eth_set_enetaddr(1,macaddr2); and added code in common/cmd_nvedit.c to update the same board info structure to be passed to the linux. else { int i; extern unsigned char macbuf[]; for (i=0; i<6; ++i) { bd->bi_enetaddr[i] = macbuf[i]; } for (i=6; i<12; ++i) { bd->bi_enet1addr[i-6] = macbuf[i]; } The problem being, the linux is getting the MAC address that was read from eeprom if I download linux and ramdisk to RAM using tftp and bootm by giving ram addresses. Linux is not getting the Mac addresses if I bootm by giving flash addresses of linux and ramdisk that are present in flash. Thanks in advance.
