Hi,
We are working on sam9x35. We made our custom board by changing externl ram DDR2-SDRAM(In evm MT47H64M16HR) to LPDDR-SDRAM(MT46H32M16LFBF) and Using serial flash at CS0(AT25DF321A-MH-Y) with same pins as EVM.After Customizing our board we need to burn the bin files(boot strap code and application) using Sabma-tool(2.16) but after executing
1)when we are executing Enable SerialflashSPI0_CS0(SerialFlash AT25/AT26 tab) following error,
E- Script error: Applet Init command has not been launched (-E- Timeout: The applet did not return.
Please check the connection and reconnect the target device.)
2)when we are executing erase all(SerialFlash AT25/AT26 tab),getting following error
E- Script error: Applet erase all command has not been launched (-E- Timeout: The applet did not return.
Please check the connection and reconnect the target device.)
above error from generic.tcl-->Generic::run file
We Thought that to run applets on board External memory should be intialized first.So We Made following Changes for lpddr-sdram((MT46H32M16LFBF) .
We changed samba source Code as per our custom board by following below link
http://www.atmel.com/Images/Atmel-42438-SAM-BA-Overview-and-Customization-Process_ApplicationNote_AT09423.pdf
We made changes in below files:
1)sam-ba2.16/tcl_lib/atsam9g15-ek/customized_board.tcl (file attached)
variable sramSize $AT91C_IRAM_SIZE // how to know this one size
variable maxBootSize [expr 24 * 1024] // how to know this one size
variable extRamVdd 0 # Vdd Memory 1.8V = 0 / Vdd Memory 3.3V = 1
variable extRamType 2 # External SDRAM = 0 / External DDR = 1 lpddr-sdram=2(this one added )
variable extRamDataBusWidth 16 ## Set bus width (16 or 32)
variable extDDRamModel 0 # Not Understood this one.kept 0
after that not implemented another lpddr intializing procedure. already ddram intializing was there and it will be called by above board parametres right.
# Initialize DDRAM (already there in customized_board.tcl )
if {[catch {GENERIC::Init $RAM::appletAddr $RAM::appletMailboxAddr $RAM::appletFileName [ $::target(comType) $::target(traceLevel) $BOARD::extRamVdd $BOARD::extRamType $BOARD::extRamDataBusWidth $BOARD::extDDRamModel]} dummy_err] }
2)applets/sam9x5/sam-ba_applets/extram/main.c (file attached)
#define BOARD_LPDDR_SIZE (512*1024*1024) // 512mb
BOARD_Configurelpddr(); //function call for ramtype 2 Declaration in board_memories.h (added)
pMailbox->argument.outputInit.memorySize = BOARD_LPDDR_SIZE;
3)sam-ba2.16/applets/sam9x5/libraries/libboard_sam9xx5-ek/source/board_memories.c (file attached)
BOARD_Configurelpddr() function Defination was written here.please find attachements.
Afrer Changing and compiling Samba sorce code binaries are created in samba/tcl-lib.but We are getting same error again.
not understanding problem with Hardware or Sam-ba tool customization.
Could you please anyone correct us. those changes are right or wrong.are there any missing modification in any files.please
find the attachments.[/]
