[U-Boot] [PATCH] NIOS2: Added DE2 board with SD support
by ivanchuklist ivanchu 08 Mar '09

08 Mar '09

Hi list, I wrote about my work with u-boot in the thread "[U-Boot] DE2 board with MMC interface (PIO based) and FAT support enabled" and i decided to post a patch. I would like to discuss the changes. I have changed the Makefile to match the binutils provided by Altera and i added the DE2 board. I have also made changes to the files cmd_mem.c to add one more command "dmmc". Because the SD card is not a memory mapped device in the bus like a flash memory, we can't deduce the direction of data (i mean when copying data to sd or from sd) with the function mmc2info(). I tried to solve this trick by using the command dmmc. I found problems at link level with cmd_mmc.o and cmd_mem.o because both files includes mmc.h, then i have two copies of the same functions in both objects files. I solved this problem by declaring extern the function mmc_init in cmd_mmc.c. I think i should post the file include/asm-nios2/arch-nios2/mmc.h and the board related files but i will wait your response. In include/asm-nios2/arch-nios2/mmc.h i implemented mmc_get_dev() and mmc_read_block() to provide access to the FAT table. The code is working with all the examples distributed by Altera in the DE2 board and it should work with any SD socket interfaced by PIO cores. diff --git a/Makefile b/Makefile index 4df4812..6501d08 100644 --- a/Makefile +++ b/Makefile @@ -163,7 +163,7 @@ ifeq ($(ARCH),nios) CROSS_COMPILE = nios-elf- endif ifeq ($(ARCH),nios2) -CROSS_COMPILE = nios2-elf- +CROSS_COMPILE = nios2-linux- endif ifeq ($(ARCH),m68k) CROSS_COMPILE = m68k-elf- @@ -3137,6 +3137,9 @@ PK1C20_config : unconfig PCI5441_config : unconfig @$(MKCONFIG) PCI5441 nios2 nios2 pci5441 psyent +DE2_config : unconfig + @$(MKCONFIG) DE2 nios2 nios2 de2 altera + #======================================================================== ## Microblaze #======================================================================== diff --git a/common/cmd_mem.c b/common/cmd_mem.c index 400cfd7..4585795 100644 --- a/common/cmd_mem.c +++ b/common/cmd_mem.c @@ -53,6 +53,7 @@ uint dp_last_length = 0x40; uint mm_last_addr, mm_last_size; static ulong base_address = 0; +static ulong mmc_direction = 0; /* Memory Display * @@ -355,6 +356,17 @@ int do_mem_cmp (cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) return rcode; } +int do_dmmc( cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) +{ + if (argc > 1) + mmc_direction = simple_strtoul(argv[1], NULL, 10); + if (mmc_direction) + printf("Mem to mmc\n"); + else + printf("Mmc to mem\n"); + return 0; +} + int do_mem_cp ( cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) { ulong addr, dest, count; @@ -405,7 +417,7 @@ int do_mem_cp ( cmd_tbl_t *cmdtp, int flag, int argc, char *argv[]) #endif #if defined(CONFIG_CMD_MMC) - if (mmc2info(dest)) { + if (mmc_direction) { int rc; puts ("Copy to MMC...

Re: [U-Boot-Users] NAND boot from file
by Charles Krinke 06 Mar '09

Dear Wolfgang: >Um... if this is JFFS2, then why not simply "fsload" + "bootm" ? Although I can format the flash in Linux and run fsinfo, ls or fsload in u-boot, there is a time of several minutes after Scanning JFFS2 FS Before ls can find the directory or fsload can attempt to load the uImage file. I am thinking that the 'flash_eraseall -j' command I am using may not be quite setup correctly with the u-boot environment. It should not take several minutes to pull a directory off a formatted flash. Here is what I do: Linux# flash_eraseall -j /dev/mtd0 Linux# mount -t jffs2 /dev/mtdblock0 /mnt/flash1 Linux# cp /uImage /mnt/flash1 Linux# ls /mnt/flash1 uImage is here, now reboot uboot> ls uImage is here, but it takes several minutes to get the listing. Fsload takes several minutes also. Can you think of what other assumptions I may be making that may be invalid? Charles

[U-Boot] FSL DDR @ 83xx
by Andre Schwarz 03 Mar '09

03 Mar '09

Kim, I'd like to change my DDR setup code since it looks like my computed values are not perfectly stable on our 8343 based board. This implies using a fake SPD and the related code to set up the controller. Is the "new" common FSL DDR setup code (cpu/mpc8xxx/ddr/*) stable for 83xx or shall I stick to cpu/mpc83xx/spd_sdram.c for a while ? regards, André MATRIX VISION GmbH, Talstraße 16, DE-71570 Oppenweiler - Registergericht: Amtsgericht Stuttgart, HRB 271090 Geschäftsführer: Gerhard Thullner, Werner Armingeon, Uwe Furtner

[U-Boot] [PATCH 1/2] smc911x: split out useful defines/functions into local header
by Mike Frysinger 25 Feb '09

25 Feb '09

The smc911x driver has a lot of useful defines/functions which can be used by pieces of code (such as example eeprom programmers). Rather than forcing each place to duplicate these defines/functions, split them out of the smdc911x driver into a local header.

[U-Boot] [PATCH] tsec: report when there is no vendor specific PHY support.
by Paul Gortmaker 18 Feb '09

18 Feb '09

Commit af1c2b84 added a generic phy support, with an ID of zero and a 32 bit mask; meaning that it will match on any PHY ID. The problem is that there is a test that checked if a matching PHY was found, and if not, it printed the non-matching ID. But since there will always be a match (on the generic PHY, worst case), this test will never trip. In the case of a misconfigured PHY address, or of a PHY that isn't explicitly supported outside of the generic support, you will never see the ID of 0xffffffff, or the ID of the real (but unsupported) chip. It will silently fall through onto the generic support. This change makes that test useful again, and ensures that the selection of generic PHY support doesn't happen without some sort of notice. It also makes it explicitly clear that the generic PHY must be last in the PHY table.

[U-Boot] [PATCH v3 0/6] i.MX31: Add NAND support and new PDK board.
by Magnus Lilja 10 Feb '09

10 Feb '09

Hi again This series of patches adds support for the NAND flash controller in the i.MX31 device and also introduces the Freescale i.MX31 PDK board. Changes since v2: - Added doc/README.mx31 (contains MC13783 SPI config documentation) - Split the PDK patch into two patches, the first introduces the board without NAND support, the second adds NAND support. - Re-ordered the series so the NAND patches are placed last - mx31_nand.c has been updated w.r.t. coding style. - There are still issues with the NAND driver (i.e. not all comments from Scott Wood have been taken care of yet). Therefore I suspect that the NAND driver is not ready for inclusion yet, the other patches should be OK. The patches are based on the current main U-boot git repo (as of Friday morning). Changes since v1: - Moved PDK board to boards/freescale/mx31pdk - Moved mxc_nd.c to driver/mtd/nand/mx31_nand.c - Moved contents of mxc_nd.h to mx31-regs.h - Cleaned up the mx31pdk.h config file after comments from this list - CONFIG_CMD_IMLS is still #undef'd but a comment is added in the config file about that. - A new patch has been inserted into the series, it makes the MC13783 SPI bus and chip select configurable. The patches are based on the current main U-boot git repo. Original intro for this series of patches: At the moment, the patch series does not add support for booting from NAND. This means that the PDK board support assumes that some other entity configures the SDRAM and loads U-boot into RAM (e.g. another bootloader or a JTAG debugger). Support for NAND boot is in progress and will be submitted later. The NAND driver is based on Freescale's Linux driver from their BSP. I've cleaned it up a bit and made the (minor) modifications necessary for U-boot. Perhaps the driver should be cleaned up even more, there are some CONFIG_MTD_MXC_* leftovers in the driver. I have tested the driver on the Litekit (small page NAND) and on the PDK (large page NAND) by having the U-boot environment placed in NAND. Regards, Magnus
