U-BOOT !!!!!!!!!!!!

[Altera_Forum]

Hi http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wacko.gif , 

that u-boot is really driving me crazy. This is what I&#39;ve done: 1- Compiled u-boot (got the .bin and the .srec) 2- Used flash programmer to program the .bin in flash (user zone) 3- Used quartus programmer to program standard.sof  4- Followed those instructions in the Using.txt But everytime I launch the nios2-console I get an error message Communication port must be specified. Use openport <port> to configure the communication port. And I&#39;m totally lost within that, It&#39;s by God bless that I succeded to write this topic Please rescue me

Hi MFM, 

 ==> flinfo Bank# 1:   Size: 0 KB in 0 Sectors Sector Start Addresses: It&#39;s time to implement your flash driver. If you have a CFI flash (and are _not_ using a data cache) you may want to try the default CFI flash driver. However, depending on the command set and your flash geometry you may have to disable the toggle bit polling (since it won&#39;t work with avalon).  Otherwise, you can grab an existing driver from another project. Please post your flash configuration (and part numbers) and I&#39;ll see if there&#39;s one I can recommend.  Best Regards, --Scott

Hi MFM, 

 I&#39;m trying to re-synchronize with this thread since I&#39;ve been away, please excuse the multiple posts ...  > Besides, I feel confused between Flash and SDRAM adresses, I can&#39;t even decide > what adresses to submit to mkimage, is the adress I&#39;ve programmed u-boot at is   Always use the address where you want the image to be loaded and executed from. In your case, SDRAM. There are two addresses you need to specify: (1) the load address, and (2) the entry point address.  The load address is address where you want u-boot to copy the kernel image. It is _not_ the addres where the .img file is loaded. You can put the .img file anywhere in memory (flash, tftp into sdram, whatever). When you run bootm, you specify the address of the .img, u-boot will then copy the kernel from the .img to the load address. If the kernel image is compressed, u-boot will decompress as it copies.  The entry point address is the address that u-boot jumps to after loading the kernel to its load address (and flushing cache, and disabling interrupts, etc). Normally, for Nios-II/uClinux, the entry point address and the load address are the same. Since the kernel start code is usually placed at the beginning of the kernel image. For other architectures/kernels the entry point may actually be at some offset from the start of the kernel image -- that&#39;s why you have the option of setting it with mkimage.  Hope this helps.  Regards, --Scott

Hi, 

could somebody tell me where to get my flash base adress http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif  The fact is that when I looked in the standard design, I&#39;ve found that ext_flash is adressed at 0x00000000 and SDRAM at 0x01000000, but when I tryed to use the nios2-flash-programmer to upload the u-boot.flash (made with bin2flash) it&#39;s always failing with the 0x00000000 base adress, contrariwise, when I choose a 0x00800000 base adress, it works but the u-boot is apparently not in the user zone (I specified --location=0x00400000) since the green led of User il not lightened and u-boot not working. I&#39;ve made that manipulation in the IDE, programmed flash in the user zone and it worked fine.

 > > Please post your flash configuration (and part numbers) and I&#39;ll see if there&#39;s one > > I can recommend.  > My flash is an AMD AM29LV065D-120R 8 MB x 8 bits  You should be able to use the existing flash driver in board/altera/common/AMDLV065D.c. If you started with the ep1c20 configuration -- it would already be built for you. Otherwise, you need to include the driver in your build -- copy the file into your board directory and add it to your makefile. Then set the flash configuration macros in your configuration header file. Here are the settings from other boards that use 065D: # define cfg_flash_base 0xwhatever /* flash base addr */# define cfg_flash_size 0x00800000 /* 8 mbyte */# define cfg_max_flash_sect 128 /* max# sects per bank */# define cfg_max_flash_banks 1 /* max# of flash banks */# define cfg_flash_erase_tout 8000 /* erase timeout (msec) */# define cfg_flash_write_tout 100 /* write timeout (msec) */# define cfg_flash_word_size unsigned char /* flash word size */  Did I tell you (in some other thread) to stub-out flash_init? For some reason I thought you were using an Altera stratix 2 development board -- which uses the LV128.  Regards, --Scott

Hi,Scott  

 My flash is AM29LV160DB and it locates in 0x800000 ,how can I choose a flash drive for it.  I use the u-boot-1.1.4 and choose the PK1C20 board . but the flash used is AM29LV065D-120R 8 MB x 8 bits.    how can I modify it to meet my Cyclone Board?

Hi scut_ak, 

 > My flash is AM29LV160DB and it locates in 0x800000 ,how can I choose a flash drive for it.  The best bet is to copy an existing driver and make whatever modifications you like. The one I would suggest is board/mvblue/flash.c -- you&#39;ll have to grab it from the u-boot project since it&#39;s not included in the sources from psyent (because it&#39;s not a nios board). The mvblue flash driver includes support for the 160D (and a few others).  I will be updating the psyent sources soon and hope to have the CFI driver fixed to work with the avalon bus (and Nios II configurations with dcache). There has been alot of churn in the u-boot CFI implementation over the past several months, but things finally seem stable. Hopefully, the CFI driver will eliminate the need for any custom flash drivers -- so it will be easier to port u-boot to a custom board.  I&#39;ll make a post once I have things ready.  Regards, --Scott

Hi MFM, 

 Your problem is:unsigned long flash_init (void) { return (CFG_FLASH_SIZE); }Which is undoubtedly due to my suggestion in an other thread to stub out that routine. See: http://forum.niosforum.com/forum/index.php...700&#entry13700 (http://forum.niosforum.com/forum/index.php?showtopic=3571&st=0&p=13700&#entry13700)  You need to restore the routine to its original state now that you&#39;re using a board with an LV065D flash device:unsigned long flash_init (void) {     int i;     unsigned long addr;     flash_info_t *fli = &flash_info;     fli->size = CFG_FLASH_SIZE;     fli->sector_count = CFG_MAX_FLASH_SECT;     fli->flash_id = FLASH_MAN_AMD + FLASH_AMDLV065D;     addr = CFG_FLASH_BASE;     for (i = 0; i < fli->sector_count; ++i) {  fli->start = addr;  addr += SECTSZ;  fli->protect = 1;     }     return (CFG_FLASH_SIZE); }This will always succeed at startup -- even if you don&#39;t provide the correct base address. If the base address is incorrect, the utilities just won&#39;t work.  Regards, --Scott

Hi, 

well, I&#39;ve figured out the following: I was overwriting the compressed image with the uncompressed one, so I changed the loadaddr to 0x0150 0000. To be carefull, I changed also the load adress and entry point to 0x0120 0000. That&#39;s fixed up the gzip compressed kernel image issue, now it&#39;s uncompressing successfully but then it hangs up: ==> tftpboot 1500000 vmlinux.img Using MAC Address 08:00:3E:26:0A:5B TFTP from server 192.168.0.183; our IP address is 192.168.0.62 Filename 'vmlinux.img'.

Hi MFM,

Just turn them off.  > well, I&#39;ve figured out the following: I was overwriting the compressed image with > the uncompressed one  That&#39;s a common scenario ... especially when bringing up a new board 8-P  > I used mkimage to convert the > /home/MFM/linux-2.6.x/arch/nios2nommu/boot/compressed/vmlinux.bin > generated using hippo&#39;s buildroot  Just to be sure ... is that the _uncompressed_ binary image? I currently don&#39;t use buildroot ... and I haven&#39;t looked buildroot through the build scripts/makefiles yet.  Regards, --Scott
