Honored ContributorU-BOOT !!!!!!!!!!!!
Hi http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wacko.gif ,
that u-boot is really driving me crazy. This is what I'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 messageCommunication port must be specified.
Use openport <port> to configure the communication port52 Replies
Altera_ForumHi MFM,
> seemingly my flash base adress is 0x800000, don't ask how I get it, I just tried it and it's fine, > where to get that information remains then a mystery to me. If you're using Nios 5.1 and the 1s40 standard configuration, your flash base address should be 0000_0000. The best bet is to follow mountain8848's suggestions and review your ptf file. > Bank# 1: Size: 0 KB in 0 Sectors Check your flash_init() routine in board/altera/common/AMDLV065D.c -- you probably still have the routine contents commented out -- I believe that's what I suggested you do to get started on the other board you were using (since you were using a different flash device). Normally, u-boot will report an error if flash_init() reports zero memory. Regards, --Scott- Altera_Forum
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'll have to grab it from the u-boot project since it's not included in the sources from psyent (because it'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'll make a post once I have things ready.

Hi MFM,
Your problem is:
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're using a board with an LV065D flash device:unsigned long flash_init (void) { return (CFG_FLASH_SIZE); }
This will always succeed at startup -- even if you don't provide the correct base address. If the base address is incorrect, the utilities just won't work. Regards, --Scottunsigned 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); } - Altera_Forum

Hi,
well, I'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's fixed up the gzip compressed kernel image issue, now it's uncompressing successfully but then it hangs up:
The other problems remain with no change although I corrected the adresses for too.
