Other Parts Discussed in Thread: TMS320DM6437
Dear Support:
Ref board : TMS320DM6437
CCS Ver : v3.3
SDK Ver : dvsdk_1_01_00_15
Q1 : Try to NAND Flash boot.
Follow the TI provide spraag0e.pdf and NANDSecondaryBoot.doc and Sample project.
Step as below :
1. Preparing Application Image for NAND Flash : Done
2. NAND Flash Write Utility : Done
3. CCS v3.3 load and run NANDboot project, verify write application image to NAND Flash success. : Done
3. Preparing Secondary Boot Loader Image for I2C Boot (nandbootAIS.bin) : Done
4. I2C EEPROM Write Utility : Fail
The messaage :
.....
Writing Data to I2C EEPROM
"...please be patient this tasks a while, thanks" <= no response.
Tested board : board REV : G and E.
Chip ver : TMX320DM6437AZWTA DA-73AC52W (board REV : E)
TMS320DM6437ZWT $NC-32AP65W (board REV : G)
Try run myself board ( Temp add EEPROM chip )
Chip ver : TMS320DM6437ZWTQ $NC-44ATV6W
The messaage :
.....
Writing Data to I2C EEPROM
"...please be patient this tasks a while, thanks"
Data Write Complete .. verify data
Warning! Write Failed
: Writing data Failed!! Error code = 276939236.
Can you please give me some hint on this issue ??
Q2 : DM6437 bootup process as RBL -> Secondboot(SBL) -> APP, Is correct ?
Have possible RBL bootuped direct load myApp (On NANDFlash) ? Or the RBL -> ( UBL -> APP [both on same NANDFlash]) ? Because myself board no have EEPROM.
If possible, How do that ? Please give me some suggestion.
Thanks.
