PROCESSOR-SDK-AM335X: NAND Flash Writer through UART Boot Loader

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3358

Hi!

I am using AM3358 processor on our custom board and RTOS SDK 5_03_00_07. I am loading the UART bootloader code through XModem and after that it code is running and asking for application file so I transferred NAND Flash writer code binary file but control is not coming to NAND Flash Writer application. I gave start address in UART boot loader code 0x402F8000 instead of 0x80000000 for NAND Flash Writer application.

I gave less RAM size for UART Bootloader code but same problem I got. If any other information required please let me know.

I am attaching cmd files for both code for your reference.

Please let me know the solution.

Hi Gaurav,

I couple of things to try:

Load UART bootloader debug build and step through boot of flash writer. This is described in software-dl.ti.com/.../index_Foundational_Components.html, Emulator based debugging of boot.
Check flash writer doesn't use SBL reserved memory. This is described in software-dl.ti.com/.../index_Foundational_Components.html, SBL and App memory map.

Frank
