It copies _itself_? Not the U-Boot payload? Heiko, is this intentional? Do we really first load the whole image, then copy the U-Boot payload to some other address, then relocate it to yet another one? > I also think I might have found out what hit tx25. > > include/configs/tx25 defines the size of u-boot which SPL will use to > load from NAND into RAM. currently it is defined thus: > > #define CONFIG_SYS_NAND_U_BOOT_SIZE 0x30000 Arghh... > Wolfgang, please try the following: > > - on u-boot-testing, branch reloc_tests, revert commit 7fab02d... > (that's "arm926ejs: fix jump to RAM nand_boot") as this 'fix' is a mistake. > > - in include/configs/tx25.h, increasing CONFIG_SYS_NAND_U_BOOT_SIZE to > 0x31000 > > Let me know if building tx25 after these two corrections makes things > better. Bingo. Both the ELDK and the CS compiled versions run fine now: with ELDK: U-Boot 2010.12-rc1-00030-g7fec359 (Nov 01 2010 - 20:13:53) U-Boot code: 81200000 -> 81224E64 BSS: -> 8122DF68 CPU: Freescale i.MX25 at 399 MHz monitor len: 0002DF68 ramsize: 02000000 TLB table at: 81ff0000 Top of RAM usable for U-Boot at: 81ff0000 Reserving 183k for U-Boot at: 81fc2000 Reserving 1024k for malloc() at: 81ec2000 Reserving 24 Bytes for Board Info at: 81ec1fe8 Reserving 92 Bytes for Global Data at: 81ec1f8c New Stack Pointer is: 81ec1f88 RAM Configuration: Bank #0: 80000000 32 MiB relocation Offset is: 00dc2000 monitor flash len: 00024E64 Now running in RAM - U-Boot at: 81fc2000 ... with CS: U-Boot 2010.12-rc1-00030-g7fec359 (Nov 01 2010 - 20:18:09) U-Boot code: 81200000 -> 812237E8 BSS: -> 8122C8F0 CPU: Freescale i.MX25 at 399 MHz monitor len: 0002C8F0 ramsize: 02000000 TLB table at: 81ff0000 Top of RAM usable for U-Boot at: 81ff0000 Reserving 178k for U-Boot at: 81fc3000 Reserving 1024k for malloc() at: 81ec3000 Reserving 24 Bytes for Board Info at: 81ec2fe8 Reserving 92 Bytes for Global Data at: 81ec2f8c New Stack Pointer is: 81ec2f88 RAM Configuration: Bank #0: 80000000 32 MiB relocation Offset is: 00dc3000 monitor flash len: 000237E8 Now running in RAM - U-Boot at: 81fc3000 ... Note that the CS tool chain gives somewhat smaller code... Thanks a lot! Guess we should submit the temporary changes now as formal patches?
