; @Title: Freescale QorIQ LS1043A RDB eMMC FLASH Programming Template
|
|
; @Description:
|
|
; eMMC FLASH is connected to eSDHC
|
|
;
|
|
; The RCW_SRC field (SDHC_BASE, 371 bits) should be 0y0 ,
|
|
; The RCW_SRC field (SDHC_EXT, 363-365 bits) also be 0y000
|
|
; This script uses SYStem.Option.HRCWOVerRide to set a custom RCW for the flash
|
|
; programming phase. This should allow access to the SoC even if the flash is
|
|
; empty/corrupted and the RCW/PBL is not valid. The RCW is a template and is not
|
|
; guaranteed to work on every board.
|
|
;
|
|
; Internal SRAM : 0x1000_1000
|
|
; eSDHC base : 0x156_0000

|
|
; temporarily override the RCW. The RCW is fetched while the boot phase and defines initial
|
|
; pinmux/serdes/qspi/nor/nand/... configurations.
|
|
; The RCW override requires to reset the SoC. Two methods are supported.
|
|
; Method 1: EnReset OFF && HRCWOVerRide ON /PORESET - do not assert the nReset line, issue a JTAG based PORESET
|
|
; Method 2: EnReset ON && HRCWOVerRide ON - assert the nReset line
|
|
; Steps - Override RCW_SRC only
|
|
; * set EnReset & HRCWOVerRide - Method 1/2
|
|
; * switch to SYStem.Mode Prepare
|
|
; * write the RCW_SRC value to EDBG:0x42000040
|
|
; * switch to SYStem.Up

; Steps - Override RCW completely
|
|
; * set EnReset & HRCWOVerRide - Method 1/2
|

; * switch to SYStem.Mode Prepare
|

; * write the RCW_SRC value HARDCODED to EDBG:0x42000040
