; @Title: Freescale QorIQ LS1043A QSPI FLASH Programming Script
|
|
; @Description:
|
|
; Example script to program a S25FS512S (Cypress) attached to CS#0 of a LS1043A
|
|
; from NXP.
|
|
;
|
|
; Internal SRAM: 0x10000000
|
|
; QuadSPI(controller) Base: 0x1550000
|
|
; FLASH BASE ADDRESS(Qspi mapped): 0x40000000
|
|
;
|
|
; Prerequisites
|
|
; * Connect Debug Cable/Combiprobe is connected
|
|
; * Set RCW-SRC to QSPI 0y001000100

; <temporarily override the RCW>
|
|
; 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
|
|
; * write the RCW itself to EDBG:0x42000000 onwards
|
