[U-Boot-Users] [PATCH] [Resubmit] lpd7a40x flash.c cleanup
by Paul Ruhland 01 Jul '04

01 Jul '04

This patch cleans up some debug code from 'board/lpd7a40x/flash.c' flash_erase(). CHANGELOG: * Patch by Paul Ruhland, 11 Jun 2004: Remove debug code from 'board/lpd7a40x/flash.c' - debugging a problem with flash_erase timing out immediately, a printf was added to display the start and stop values of the timer to the console. Timer functions were changed to see if it was particular to any one method. Problem turned out to be in the timer implemention which was fixed prior to submitting original board support patch. Unfortunately, backing out the above changes was overlooked in that patch. This patch restores the flash_erase function to its original state. -- Paul Ruhland <pruhland(a)microwavedata.com> Software Engineer Microwave Data Systems Rochester, NY 16420

[U-Boot-Users] necessary fix for ARM u-boot 1.1.1 and GCC3.4.0.
by Woodruff, Richard 01 Jul '04

01 Jul '04

Hey all, I just found that lib_arm/board.c:start_armboot()'s GCC3.4.0 generated code sequence breaks ARM u-boot's. I am using the GCC3.4.0 which CodeSourcery put out. I have found what appears to be a fix. A compiler optimization barrier needs to be inserted after gd (AKA R8) is initialized. See the below snippit. With out this barrier gd is calculated into a temporary register, and when the gd->bd is actually attempted an unitilized R8 is used causing a fatal abort. Regards, Richard W. ------------------------------------- void start_armboot (void) { DECLARE_GLOBAL_DATA_PTR; ulong size; init_fnc_t **init_fnc_ptr; char *s; #if defined(CONFIG_VFD) unsigned long addr; #endif /* Pointer is writable since we allocated a register for it */ gd = (gd_t*)(_armboot_start - CFG_MALLOC_LEN - sizeof(gd_t)); __asm__ __volatile__("": : :"memory");/* compiler please write out gd to R8 now before using again */ memset ((void*)gd, 0, sizeof (gd_t)); gd->bd = (bd_t*)((char*)gd - sizeof(bd_t)); memset (gd->bd, 0, sizeof (bd_t));

[U-Boot-Users] VxWorks under u-boot
by Shlomo Kut 01 Jul '04

01 Jul '04

Hi, I wish to create a gzipped bootable image from a vxworks ELF32 file. How do I go about doing this using mkimage so that the bootm command can unzip and boot it. Has anybody got a mkimage binary that runs under windows? regards, Shlomo Kut Vyyo Ltd POB 45017 Jerusalem 91450 Israel +972-2-5889822

[U-Boot-Users] How to generalize SDRAM support for MPC5200 and MGT5100?
by Mark Jonas 01 Jul '04

01 Jul '04

Hello, while porting U-Boot to Total5200 I thought that it would be nice if all MPC5200 and MGT5100 platforms could share their SDRAM initialization code. In fact this is already done but by means of code duplication. So far most people (everybody?) simply copied the board/icecube/icecube.c and took it SDRAM init code unchanged. And if the SDRAM chips themself were matching the appropriate mt4*-75.h file was copied as well. So how can we move the SDRAM init functions from the board directory to the drivers or the cpu/mpc5xxx directory? (I think cpu/mpc5xxx would be the better match) In the Total5200 port I already went half way but taking the SDRAM init functions out from board/total/total5200.c to board/total5200/sdram.*. I did not put it into cpu/mpc5xxx because if I did so I wanted to have a smart solution in regards to coupling that with the SDRAM paramter includes (mt48lc16m16a2-75.h, mt46v16m16-75.h and mt48lc32m16a2-75.h). Does anybody have an idea how we can make this generic for all MPC5200 and MGT5100 boards? Regards Mark

[U-Boot-Users] u-boot memory setup
by epatrizi 01 Jul '04

01 Jul '04

For a PPC7410 processor, I see where the BAT registers are setup in start.S before the MMU is turned on. I cannot fit all resources for my board in the four available DBAT's. I could not find any reference to PTE tables being setup anywhere. Does u-boot setup PTE tables at this point in the code or somewhere later, or does it expect everything to fit in the BAT registers?

hi, I have added usb mass storage for at91rm9200dk board and it works well except the usbboot functionnality. My DiskOnkey is recognized as a dos partiotion and i can read the content with usb read. I want to boot a linux uImage on a DiskOnkey but i've encountered problems to create a bootable diskonkey with uImage on my w2k pc. Does anybody had the same problem? How can i do to put my Uimage on the diskonkey and use usbboot?

[U-Boot-Users] eepro100 driver is compatible with Intel 82551ER controller?
by Shawn 01 Jul '04

01 Jul '04

Hi, Does anybody know that the eepro100 driver in u-boot is compatible with Intel 82551ER fast ethernet controller? >From "Intel(R) 8255x 10/100 Mbps Ethernet Controller Family Open Source Software Developer Manual", it seems compatible. "This document is intended for use as a software technical reference manual for the Intel� 10/100 Mbps Fast Ethernet controller family, which includes the 82557, 82558, 82559, 82550, and 82551, as well as the 82562 Platform LAN Connect device. It also contains information for several PCI LAN adapters based on these devices: Intel� EtherExpress� PRO/100+, Intel� EtherExpress� PRO/100B Wake on LAN (WOL), Intel� EtherExpress� PRO/100B, and Intel� EtherExpress� PRO/10+."
