[U-Boot] uBoot Debug: GPIO Toggling does not working over 8536DS uboot

Project details: CPU: MPC8536DS [Core E500, Freescale] Flash: 16MB [50MHz Local bus Clk) DDR: 1G (SODIMM, 400 MHz) Baord: Network Evaluation Cutom MPC8536E Board U-Boot Debug Issue (GPIO Toggling code help) _________________________ -> as i am not able to debug uboot over jtag and the CW tool till now, 　[MPC8536 CPU Suoort to the CW is not available now it will be released in future.] so i have to debug it via the printf statments meanwhile after the UART initialization get over. But till when the UART initialization is not done so ihave to check the Uboot process via the GPIO Togging. ;) So when i wrote u-boot.bin file to the Flash via Jtag CW FlashProgrammer tool, and power on the SW of te board it does not bootup and the GPIO toggling is not over yet what i have to do .. is my code to toggle the GPIO is wrong or i am mistaking anything. (This code i am testing over MPC8536DS Calamari baord, not working there too) /cpu/mpc85xx/statrt.S ..... .... .section .bootpg,"ax" .globl _start_e500 _start_e500: /* 20090520 DEBUG LED Code start */ lis r2,ADR_CFG_GPIO@h ori r2,r2,ADR_CFG_GPIO@l lis r3,DIR_GPIO@h ori r3,r3,DIR_GPIO@l stw r3,0(r2) isync msync lis r2,ADR_GPIO@h ori r2,r2,ADR_GPIO@l lis r3,DAT_GPIO@h ori r3,r3,DAT_GPIO@l isync msync _T_LED: /* xori r1,r1,0xFFFF */ stw r3,0(r2) isync msync b _T_LED /* TED 20090520 DEBUG LED Code End */ /* clear registers/arrays not reset by hardware */ /* L1 */ li r0,2 mtspr L1CSR0,r0 /* invalidate d-cache */ mtspr L1CSR1,r0 /* invalidate i-cache */ mfspr r1,DBSR mtspr DBSR,r1 /* Clear all valid bits */ ..... .... and i declared the used macro in the file ./include/configs/MPC8536DS.h ....... .... #define ADR_CFG_GPIO 0xFF70FC00 /* GPIO LED Configuration Register address */ #define ADR_GPIO 0xFF70FC08 /* GPIO LED Data Register */ #define DIR_GPIO 0xFFFFFFFF /* GPIO DIRECTION though it is GPIO [0-15] */ #define DAT_GPIO 0xF28FF28F /* GPIO Data GPIO[6-8] will set as toggle alternate */ ..... ........ i tried setting as too #define DIR_GPIO 0x03800000 /* Only GPIO[6:8] */ #define DAT_GPIO 0x02800000 But not workied for me :( isync msync too not worked i put this after I cache D Cache disable too please suggest me how to debug the GPIO toggling code and the process of debugging uboot. -> also suggest me any Application note or manual over the PPC Assembly coding manual. * In case we cannot put this code here so what is the method to check the Uboot activity following like till where uboot does well or it hangs arround and after this and that kind of stuff? and from when we can do toggling the GPIO's ---------------------------------------------------------------------------------------- waiting for the reply this time more eagerly ..W.w.W.. --- Ashish Agarwal ★━━━━━━━━━・:*:*:・゜・:*:*:・★☆★ 　アガルワル　アシッシュ ★☆★・:*:*:・゜・:*:*:・━━━━━━━━━★

[U-Boot] Which U-Boot releases have Device Tree support
by cmfairfa＠rockwellcollins.com 21 May '09

21 May '09

We bought a MPC8360E-RDK development kit to develop applications under MontaVista CGE5.0. We were toldby the consultant whose doing our board LSP that the U-Boot version that came with the development kit did not have device tree support. The consultant upgraded the U-Boot to a version that has device tree support, but he says he doesn't have the source code for the U-Boot version. I need the source to make certain updates. Which U-Boot version can I download that has device tree support? Thanks. Christopher M.

[U-Boot] LZMA warnings in cmd_bootm
by Mike Frysinger 20 May '09

20 May '09

the LZMA code that was added to cmd_bootm causes a warning: cmd_bootm.c: In function 'bootm_load_os': cmd_bootm.c:394: warning: passing argument 2 of 'lzmaBuffToBuffDecompress' from incompatible pointer type this is because the code passes in a pointer to unc_len which is an unsigned int, but the decompress routine expects a pointer to a size_t. could you take a look ? -mike
