[U-Boot-Users] slow memory running from flash.
by David Updegraff 04 Nov '05

04 Nov '05

Hi. I have an MPC8343 that runs its memory _VERY_ slowly when I run code from flash. Identical u-boot code loaded into RAM and run from there is fine, and 10x or more faster for memcopy and dma_xfer. I.e. the IMMBAR setup registers for memory are identical. Eg. the 'relocate_code()' routine takes 5 seconds if i am running from flash, but negligible time if running from RAM. The only difference in u-boot code is that when running from ram, the remap_flash_by_XYZ games in start.S are not played. All dcache issues are the same either way. I wonder if anyone has a clue for me about why this might be? -dbu.

[U-Boot-Users] u-boot on i.MX21
by Marco Cavallini 04 Nov '05

Hello, I'd like to know if u-boot has been ported on motorola MX21ads (M9328MX21ADS), I found a small thread in the ML talking about a patch but I'm unable to find it. BTW I already tried using the mx1ads_config without success, and mx1fs2_config that is broken and do not build. Any hint will be appreciated.

[U-Boot-Users] NetConsole tstc problems
by Brian Prodoehl 02 Nov '05

02 Nov '05

Has anyone else experienced problems with NetConsole's tstc? In particular, defining CONFIG_BOOT_RETRY_TIME makes NetConsole almost unusable for me, because then readline() in main.c blocks on tstc and the result (for me, at least) is that NetConsole accepts a character every second or so. For everything that doesn't depend on tstc, NetConsole works beautifully for me. I'm just wondering if anyone else has seen problems, or if anyone has suggestions on how to make tstc less of a show-stopper (something I haven't been able to accomplish). Brian Prodoehl

[U-Boot-Users] NAND flash support
by Terence Soh 02 Nov '05

02 Nov '05

Hi, Correct me if I'm wrong but u-boot only support 512 byte page size nand flash components. Is there going to be any nand flash driver support for 2048 bytes (8-bit data bus) page size components? Thanks, Terence.
