[U-Boot-Users] Strange behavior in UPM
by Alemao 29 Jul '08

29 Jul '08

Hi all, I have a board based on the MPC8360E-RDK, and im trying to make NAND at local bus works with UPM. I put the scope to see what was going wrong and I got this: ___ - the waveform in LGPL1/3 (nand CLE/ALE) should be ___| |___ ___ ___ but was |__| My question is: is there any regs different from those that program the UPM (BRx, ORx) that can affect and cause this behavior? Of course, supposing the UPM array in u-boot/board/freescale/mpc8360erdk/nand.c is correct, that i think it is. Im using the same configuration located at u-boot/include/configs/MPC8360ERDK.h /* * NAND flash on the local bus */ #define CONFIG_CMD_NAND 1 #define CONFIG_NAND_FSL_UPM 1 #define CFG_NAND_BASE 0x60000000 #define CFG_MAX_NAND_DEVICE 1 #define NAND_MAX_CHIPS 1 #define CONFIG_MTD_NAND_VERIFY_WRITE #define CFG_LBLAWBAR1_PRELIM CFG_NAND_BASE /* Window base at flash base */ #define CFG_LBLAWAR1_PRELIM 0x8000001b /* Access window size 4K ??? */ /* Port size 8 bit, UPMA */ #define CFG_BR1_PRELIM (CFG_NAND_BASE | 0x00000881) #define CFG_OR1_PRELIM 0xfc000001 One detail, im using u-boot-1.1.4 and i got the codes for UPM and NAND from u-boot-1.3.4-rc1. Cheers, -- Alemao

[U-Boot-Users] get_timer on ppc and bugs related to calling it (fsl_i2c)
by Kumar Gala 29 Jul '08

29 Jul '08

In debugging moving the bss outside of the image on 85xx I run into in issue with the SPD code using fsl_i2c before we are running in ram and setup the BSS. It looks like i2c_wait4bus() [in fsl_i2c.c] calls get_timer(). get_timer implemented in lib_ppc/interrupts.c and uses a global timestamp that exists in the BSS. This seems pretty bad in that we have been just getting a bogus value for timestamp out of flash. Luckily we don't write timestamp until interrupts are enabled and at that point we've relocated to memory. However it seems like fsl_i2c.c should NOT be using get_timer(). Is there another global interface to get relative time that we can just use time base for? - k
