Hello Marco, my Board doesn't have any Software, the Flash is empty and so i start from the internal ROM - clearly. But now i must do a Download on the serial Port of loader.bin which then does a serial Download of u-boot.bin. This is the Atmel described way to initialize a "new" System or to do an Update. But with the original u-boot Sources 1.1.1 or 1.1.4 the generated u-boot.bin doesn't run, the Atmel delivered binary u-boot.bin does. So i'm looking what to do with u-boot, so that it is loadable like the Atmel one. Who knows if there are any #defines to set (especially for this CPU/Platform) or where any Dokumentation for this can be found ?

[U-Boot-Users] Loadb issue
by Banajit Goswami 19 Jul '06

19 Jul '06

Hi All, I am a new member to this mailing list. I am porting u-boot to a arm926ej board. I have a serial port which I am trying to use to download a binary image. But I am not able to do so. I am trying to use loadb and loads and both seems to be failing. Here is a typical sequence i followed 1) Boot-up the board 2) Connected to Hyperterminal (tried minicom, cu, kermit and dnw) with 8N1 and hw-flw control as "none". 3) at u-boot command prompt gave following command => loadb 0x60008000 115200 4) From hyperterminal, Transfer->send file with protocol as kermit, selected the file and tried sending, but failed. Everytime hyperterminal poped up "error limit exceeded". # loadb ## Ready for binary (kermit) download to 0x60008000 at 115200 bps.. When tried looking the point where it is geting stuck, I saw u-boot waiting in the while loop looking for the 'START_CHAR' in the following section of code: k_recv(){ ..... .... for (;;) { switch (getc ()) { case START_CHAR: /* start packet */ goto START; case ETX_CHAR: /* ^C waiting for packet */ return (0); default: ; } } .... ... } I am not sure how to use 'loadb' and 'loads'. Read a few docs about uses though, none explained what needs to be done in implementation part. Can anyone give me some pointer, as in, any board which has implemeted and using any of the commands? What might have gone wrong here?? Or any other commands I can use for serial download of binary image? Thanks in advance Banajit

Hello Wolfgang, that is an important Information: The original u-boot is build for running out of the NOR -Flash and not for serial Download and run out of RAM - did i understand correctly ? The Atmel Evaluation Board Docs describe a way of A) X-Modem a loader.bin to RAM and start it B) X-Modem an u-boot.bin to RAM and start it C) Kermit with this boot.bin and flash this with u-boot D) Kermit a u-boot.gz and flash this After configuring the cpu to "boot external" it then runs out of the flash. The Atmel Docs also write to generate the binary only delivered Files the two steps: 1) Patch the Source for Support of the soldered Flash Chip 2) Compile it But with your words, if i do so only a Version of u-boot for direct flashing to the NOR Flash Chip is generated. Is there a way to generate an u-boot Version for the Way Atmel describes in any Version or have i to ask Atmel how they patched their Version ?

Hello Wolfgang, AFAIK the AT91RM9200 Boot Sequence only allows 16k-4k size for the first Programm, E.g. the loader.bin. The u-boot.bin ist about 92k, so it cant't be loaded directly. First the loader.bin ist executed which initializes the external SDRAM an it then loads u-boot.bin to external SDRAM. How can the u-boot be configured to be used so, i didn't find any hints.

Hello, for the first step of reproducing a runnig u-boot i use the original Atmel Board. Here the u-boot does nothing after load with loader.bin. The Atmel delivered u-boot.bin does normal work. U-boot is build with the desribed steps without any Error Messages. make at91rm9200dk_config make all Then X-Modem the loader.bin and then X-Modem the u-boot.bin to the AT91RM9200-EK and after this nothing happens. Are there further Things to configure, i didn't read ? THX Thomas > -----Ursprüngliche Nachricht----- > Von: wd(a)denx.de [mailto:wd@denx.de] > Gesendet: Mittwoch, 19.
