ONBOARD FLASH Support + +FLASH support is provided for the onboard FLASH chip Bootrom area. +U-Boot is loaded into either the ROM boot region of the FLASH chip, +after first being boot-strapped from a pre-progammed AMD29F040 PLCC +bootrom. The PLCC needs to be programmed with a ROM burner using +AMD 29F040 ROM parts and the u-boot.bin or u-boot.hex (S-Record) +images. + +The PLCC overlays this same region of flash as the onboard FLASH, +the jumper J100 is a chip-select for which flash chip you want to +progam. When jumper J100 is connected to pins 2-3, you boot from +PLCC FLASH. + +To bringup a system, simply flash a flash an AMD29F040 PLCC +bootrom, and put this in the PLCC socket. Move jumper J100 to +pins 2-3 and boot from the PLCC. + + +Now, while the system is running, move Jumper J100 to +pins 1-2 and follow the procedure below to FLASH a bootrom +(u-boot.bin) image into the onboard bootrom region (AMD29LV160DB): + +tftp 100000 u-boot.bin +protect off FFF00000 FFF7FFFF +erase FFF00000 FFF7FFFF +cp.b 100000 FFF00000 \$(filesize)\ + + +Here is an example: + +=>tftp 100000 u-boot.bin +eth_halt +eth0: DC21143 Ethernet adapter(bus=0, device=13, func=0) +DEC Ethernet iobase=0x80000000 +ARP broadcast 1 +Filename 'u-boot.bin'. +Load address: 0x100000 +Loading: ######################### +done +Bytes transferred = 123220 (1e154 hex) +eth_halt +=>protect off FFF00000 FFF7FFFF +Un-Protected 8 sectors +=>erase FFF00000 FFF7FFFF +Erase Flash from 0xfff00000 to 0xfff7ffff +Erase FLASH[PLCC_BOOT] -8 sectors:........ done +Erased 8 sectors +=>cp.b 100000 FFF00000 1e154 +Copy to Flash...
