Mark, The answer lies in the top level 'config.mk'. Look for the definition of 'BFD_ROOT_DIR' and adjust according to your cross compiler. -----Original Message----- From: Jonas Mark-r50740 [mailto:Mark.Jonas@motorola.com] Sent: Friday, May 02, 2003 9:35 AM To: u-boot-users(a)lists.sourceforge.net Subject: [U-Boot-Users] astest.c: 'true' undeclared Hello, I have problems compiling U-Boot.

[U-Boot-Users] MPCFADS860T -- any active uboot developers?
by Nye Liu 01 May '03

01 May '03

I have u-boot up and running on a MPC860T-FADS eval board, but it is extremely unstable... are there active FADS developers using this board currently? Also, Wolfgang, I have one or two minor patches for this board, but I'm not sure if the differences are intentional. One of the patches adds a FLASH_ internal define to flash.h; last time I did this (in ppc-boot) you indicated not to add any more of those.. what is the policy for adding those in u-boot? -- Nye Liu nliu(a)mrv.com (818) 772-6235x248 "Who would be stupid enough to quote a fictitious character?" -- Don Quixote

RE: [U-Boot-Users] AMD MirrorBit FLASH Support?
by Brad Kemp 01 May '03

Tien After looking closer at your application, you will need to add support for 64 bits flash. Search the code for FLASH_CFI_32BIT. It is mostly used in case statements. Add the appropriate code for FLASH_CFI_64BIT. There is one loop that loop you will need to change The FLASH_CFI_32BIT to FLASH_CFI_64BIT. Also the cfiword_t and cfiptr_t unions will need the addition of long longs.

RE: [U-Boot-Users] AMD MirrorBit FLASH Support?
by Brad Kemp 01 May '03

Tien I have used this driver on 2 other boards with strataflash The boards have different flash widths. The only application specific part is the location of the uboot environment. The config for the ppmc8260 may not fall on a sector boundary or be wrong. If the saveenv fails, check that.

RE: [U-Boot-Users] AMD MirrorBit FLASH Support?

Hi Brad, I have a custom board MPC8260 that uses the flash width 64 bits with 4 chips (28F640J3) as it describes in the application note Intel 292263-002 (http://www.intel.com/design/flcomp/applnots/29226302.pdf). Do you think that I can use the flash driver ppmc8260/strataflash.c directly without modification?

There is CFI support for the Intel command set in ppmc8260/strataflash.c and esd/cpic440/strataflash.c. This driver correctly sizes the flash width and number of chips. What is missing is an abstraction to support multiple command sets.

[U-Boot-Users] CodeWarrior U-Boot debug
by Roel Loeffen 01 May '03

01 May '03

Hello, Has anyone of you ever used MetroWerks CodeWarrior to debug U-Boot? After I've succesfuly compiled the u-boot ELF and binairy I've programmed my flash with the binairy. Next, I've made a CodeWarrior project using the ELF file output of the GNU Compiler. I can connect to the PPC and I can view memory, but when I break the running process, the cpu is always stuck at address 0x800 (floating point exception). Also I cannot view the code in CodeWarrior?? Can someone help me? Thx Roel
