[U-Boot-Users] Problem with the u-boot1.1.3 booting the uclinux from the jffs2 partition
by DeviPrasad Natesan 16 Mar '06

Hi all, I am presently using microblaze target and boot the uClinux using u-boot (version 1.1.3) from the read-only root file system (mounted read-only by the kernel command line parameter) from the directory /boot. Everything works fine. Just for debugging and testing few application, i mount the root as read-write and after the uclinux kernel is up, i FTP'ed a big file like the kernel or any utilities. I can run the ftp'ed application properly and i can do a ftp get from the target and the image matches. Everything seems fine until i reboot. When the system is rebooted, the u-boot when it starts, cannot find the new kernel and fails after getting the following error. ============================================== DRAM: 32 MB FLASH: 8 MB Hit any key to stop autoboot: 0 ### JFFS2 loading 'boot/linux.uboot' to 0x25000000 Scanning JFFS2 FS: ../ Unknown node type: e001 len 46 offset 0x581c80 Unknown node type: e001 len 46 offset 0x581cf8 Unknown node type: e001 len 45 offset 0x581d70 Unknown node type: e001 len 45 offset 0x581e60 Unknown node type: e001 len 45 offset 0x581ed8 Unknown node type: e001 len 45 offset 0x581f50 Unknown node type: e001 len 45 offset 0x581fc8 Unknown node type: e001 len 45 offset 0x582040 Unknown node type: e001 len 45 offset 0x5820b8 Unknown node type: e001 len 45 offset 0x582130 Unknown node type: e001 len 45 offset 0x5821a8 Unknown node type: e001 len 46 offset 0x582220 ..... done. find_inode failed for name=boot load: Failed to find inode ### JFFS2 LOAD ERROR<0> for boot/linux.uboot! =========================================== To make sure that the MTD drivers works ok, i tested the whole partition upgrade using netflash utility and it works perfectly fine and the u-boot can boot the kernel. Is this kinda behaviour as expected or in other words does the u-boot expects the root-file sytem to be RO only. I am not sure is it becos of the problem in the uclinux jffs2 or not. I did include the "CFG_JFFS2_SORT_FRAGMENTS" in the u-boot and checked and still got the same problem. Any pointers regarding this will be appreciated. Thanx - Prasad

[U-Boot-Users] 8xx spi support broken
by Antonio Di Bacco 16 Mar '06

16 Mar '06

I enabled the SPI COMMAND in u-boot for an 8xx and it doesn't compile. Chipset in spi_xfer is not managed correctly!?! I'm going to modify this code. Anyone is interested? I know I shouldn't post on this mailing list for u-boot but where can I post? Bye, Antonio.

[U-Boot-Users] Marvell DB64460-BP I2C_BOOT/Swap_BOOT Issue
by Sam Song 16 Mar '06

16 Mar '06

Hi all, I tried booting the target with I2C_BOOT disabled and failed - No any serial output. Then I programmed the same image on the Large Flash area 0xf4f00000 and inserted JP46 to swap 8-bit Boot Source to 32-bit Boot Source. I got the following output: U-Boot 1.1.3 (Mar 16 2006 - 09:12:14)--Marvell DB64460 (1.0) CPU: MPC7447A v1.1 @ 1396.500 MHz BOARD: DB64460 DRAM: SPD Checksum ok! -- DIMM1 has 1 banks -- DIMM2 has 0 banks ECC Initialization of Bank 0: PASS CAS Latency = 2.5 tRP = 3 tRAS = 6 tRCD=3 *** ONLY the first 256MB DRAM memory are used out of the 512MB Sure, I did some changes on CPU type detection and clock setting only to make it work with I2C_BOOT enabled. Questions: 1. How to make I2C_BOOT disable case work? If would better with 8-bit default boot FLASH. 2. Anyone tried booting Swap BOOT successful on this board?

[U-Boot-Users] USBTTY with Windows problem
by Vovan 15 Mar '06

15 Mar '06

Hello , I work with some OMAP310 based board and I need to get u-boot usbtty console working in windows. In linux it works fine, but with windows driver (usbser.sys) it hangs when sending from u-boot to host amount of data greater than USBTTY_BUFFER_SIZE. When reconnecting again - the rest of data is recieved. Do anybody know where to start ? Usbmon shows that after USBTTY_BUFFER_SIZE data is received to host all the rest usb packets are empty. So console hangs even when typing HELP command in it. -- Best regards, Vovan

[U-Boot-Users] mii_send error or at least strange
by Antonio Di Bacco 15 Mar '06

I had a look to mii_send code in u-boot/cpu/mpc8xx/fec.c . It supports both FEC1 and FEC2 but anyway it seems to write always register mii-data of FEC1, look here: /* send command to phy using mii, wait for result */ static uint mii_send(uint mii_cmd) { uint mii_reply; volatile fec_t *ep; int cnt; ep = &(((immap_t *)CFG_IMMR)->im_cpm.cp_fec); ep->fec_mii_data = mii_cmd; /* command to phy */ /* wait for mii complete */ cnt = 0; while (!(ep->fec_ievent & FEC_ENET_MII)) { if (++cnt > 1000) { printf("mii_send STUCK!\n"); break; } } mii_reply = ep->fec_mii_data; /* result from phy */ ep->fec_ievent = FEC_ENET_MII; /* clear MII complete */ #if 0 printf("%s[%d] %s: sent=0x%8.8x, reply=0x%8.8x\n", __FILE__,__LINE__,__FUNCTION__,mii_cmd,mii_reply); #endif return (mii_reply & 0xffff); /* data read from phy */ }

I have two FECs, when I launch the tftp, it tries with first FEC then it tries with the FEC2 but gives a warning when using FEC2: "mii_send STUCK" Bye.
