[U-Boot] [PATCH 1/2] dfu:ext4:fix Fix ext4{read|write} command formatting
by Lukasz Majewski 08 Jul '13

08 Jul '13

In the following commit: "dfu: Support larger than memory transfers." SHA1: ea2453d56b8860dbd18a3c517531ffc8dcb5c839 The ext4{read|write} command formatting has been changed. It removed a write mandatory [sizebytes] parameter. It extents DFU_FS_EXT4 case at mmc_file_op to provide mandatory parameter for DFU write.

[U-Boot] nds32: ag101/ag102: Inconsistent timer3 counter unit?
by Axel Lin 08 Jul '13

08 Jul '13

Hi Macpaul, For the case CONFIG_FTTMR010_EXT_CLK is not defined: In reset_timer_masked(): lastdec = readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2); In get_timer_masked(): ulong now = readl(&tmr->timer3_counter) / (CONFIG_SYS_CLK_FREQ / 2 / 1024); The code looks strange. (Why one needs to be divided by 1024 and the other one does not?) I'm not sure which one is correct. Regards, Axel

[U-Boot] [U-boot] monitor length question
by TigerLiu＠viatech.com.cn 05 Jul '13

05 Jul '13

Hi, experts: I am studying u-boot latest code now. I have a question about monitor length. 1. in board_init_f() function in arch\arm\lib\board.c Gd->mon_len = _bss_end_ofs; 2. in board_init_r() function in arch\arm\lib\board.c 　　Monitor_flash_len = _end_ofs; Because _end_ofs < _bss_end_ofs, so it confused me! Why need to discard some data when re-calculating monitor_in board_init_r() function. Best wishes,

[U-Boot] test HYP mode in arch/arm/cpu/armv7/start.S
by TigerLiu＠viatech.com.cn 05 Jul '13

05 Jul '13

Hi, experts: I found it would determine whether CPU was in HYP mode or not before switching to SVC mode in reset handler. So, why need to test HYP mode? So, which case could cause CPU in HYP mode during U-Boot boot stage? Best wishes,

[U-Boot] How to prepare a MTD partion?
by Woody Wu 05 Jul '13

05 Jul '13

Hi, After defined MTD partions in kernel and u-boot, what's the next steps to make it mountable? I have defined two data partitions in MTD out of my NAND flash, each of which has size of about 800M. Then I want to make them as Yaffs2 and j2ffs and mount them to use. In PC linux, I know there are something like mkfs.xxx, which seems not the case for MTD partitions. So, can anyone be so kind to tell me what are steps I need to do in u-boot and out-of-uboot? Thanks in advance! -- I can't go back to yesterday - because I was a different person then
