[U-Boot-Users] Adding a new board to the u-boot project
by Ronald Madrid 06 May '08

06 May '08

I'm developing a board based on the MPC8313 and want to have my code included in the u-boot project, but have a few questions. I have created in u-boot-1.3.2 my own folder in the board directory and all appropriate config files. I have also edited the Makefile on the top level. Everything builds for my board's u-boot, but here are my questions. I have to create a new folder in the nand_spl/board folder as my board supports NAND flash. Is that ok? Also, to add NAND support I have to edit the cpu/mpc83xx/start.S file. Is this allowed? After I get my code working is there a specific person that I forward the patches to?

[U-Boot-Users] U-boot-1.3.2-rc2 Error when Building with CONFIG_FIT and CONFIG_LOGBUFFER
by Grant Erickson 05 May '08

05 May '08

I am attempting to use CONFIG_FIT in u-boot-1.3.3-rc2 on the AMCC Kilauea board and, when used in conjunction with CONFIG_LOGBUFFER get the following compilation errors in common/cmd_bootm.c: cmd_bootm.c: In function 'fit_check_kernel': cmd_bootm.c:438: error: 'kbd' undeclared (first use in this function) cmd_bootm.c:438: error: (Each undeclared identifier is reported only once cmd_bootm.c:438: error: for each function it appears in.) cmd_bootm.c:440: error: 'initrd_high' undeclared (first use in this function) cmd_bootm.c:440: error: 'LOGBUFF_LEN' undeclared (first use in this function) cmd_bootm.c:440: error: 'LOGBUFF_OVERHEAD' undeclared (first use in this function) Are these known/expected errors? Looking at the source, it seems like this got patched into the wrong place or is missing part of the patch. Regards, Grant Erickson

[U-Boot-Users] [PATCH] add config options for VSC8601 RGMII PHY - 2nd try
by Andre Schwarz 05 May '08

05 May '08

The Vitesse VSC8601 RGMII PHY has internal delay for both Rx and Tx clock lines. They are configured using 2 bits in extended register 0x17. Therefore CFG_VSC8601_SKEW_TX and CFG_VSC8601_SKEW_RX have been introduced with valid values 0-3 giving 0.0, 1.4,1.7 and 2.0ns delay.

[U-Boot-Users] question bout exception happen
by loody 05 May '08

05 May '08

Dear all: I have some question about what arm will do while exceptions happen. In the document, ARM Architecture Reference Manual located at http://www.arm.com/miscPDFs/14128.pdf, there are some actions will be done when IRQ interrupt happened, A2.6.8. Below is excerpted from it: R14_irq = address of next instruction to be executed + 4 SPSR_irq = CPSR CPSR[4:0] = 0b10010 /* Enter IRQ mode */ CPSR[5] = 0 /* Execute in ARM state */ /* CPSR[6] is unchanged */ CPSR[7] = 1 /* Disable normal interrupts */ CPSR[8] = 1 /* Disable Imprecise Data Aborts (v6 only) */ CPSR[9] = CP15_reg1_EEbit /* Endianness on exception entry */ if VE==0 then if high vectors configured then PC = 0xFFFF0018 else PC = 0x00000018 else PC = IMPLEMENTATION DEFINED /* see page A2-26 */ To return after servicing the interrupt, use: SUBS PC,R14,#4 Do these actions have to be done by software or cpu will automatically finish them? Appreciate your help, miloody

[U-Boot-Users] commit 22069215 - [MIPS] Fix $gp usage
by Wolfgang Denk 05 May '08

05 May '08

Dear Shinya, I think we need your help with the current MIPS code; it seems that this commit is causing problems: commit 22069215eb7adf5a3888bf7c7784ea9d70a72cd0 Author: Shinya Kuribayashi <shinya.kuribayashi(a)necel.com> Date: Sun Oct 21 10:55:36 2007 +0900 [MIPS] Fix $gp usage The issue is with "cpu/mips/start.S"; with older toolchains (like ELDK 3.1.1 which uses binutils 2.14, we get: start.S: Assembler messages: start.S:348: Error: relocation out of range make[1]: *** [start.o] Error 1 With ELDK 4.0 and 4.1 (binutils 2.16.1) we get no erros, but these warnigns: cache.S: Assembler messages: cache.S:243: Warning: Pretending global symbol used as branch target is local. cache.S:250: Warning: Pretending global symbol used as branch target is local. Jean-Christophe Plagniol-Villard reports that he sees no problems (no errors nor warnings) with binutils 2.18 I wonder if it was possible to come up with a version of the code that builds with somewhat older versions of the toolchains, too? Thanks in advance.
