; @Title: Serial flash script for TCC8030-CA7 on TCC803x EVB (RAM)
|
|
; @Description:
|
|
; MX25L256 is connected to the SFMC controller
|
|
;
|
|
; SRAM: 0xC0001000
|
|
; SFMC: 0x1B9100000
|
|
; SFMC memory mapped ADDRESS: 0xD0000000
|
|
;
|
|
; Prerequisites:
|
|
; * Power-on-reset is required after debugging the CA53 or CM4
|
|
; * Connect the DC 12V/10A power adapter to the DC-JACK (J7) on main board.
|
|
; * Connect Debug Cable to JTAG header (J10D1) on TCC8030 CPU board.
|
|
; * Use board with Android SDK firmware and default SNOR boot mode.
