Part Number: STARTERWARE-SITARA
Hello,
We are using Am335x based custom board. In this, we want to boot the board from NOR.
We are using bootloader code for this.
We have flashed the code into NOR, but booting is not started. We are getting "C" on the debug console.
We have also generated the trace vector sheet, but we are not able to analyze the problem.
Our tracing vector file is as following:
CONTROL: device_id = 0x2b94402e
* AM335x family
* Silicon Revision 2.1
PRM_DEVICE: PRM_RSTST = 0x00000001
* Bit 0 : GLOBAL_COLD_RST
CONTROL: control_status = 0x0040031b
* SYSBOOT[15:14] = 01b (24 MHz)
* SYSBOOT[11:10] = 00b No GPMC CS0 addr/data muxing
* Device Type = General Purpose (GP)
* SYSBOOT[7:6] = 00b MII (EMAC boot modes only)
* SYSBOOT[5] = 0 CLKOUT1 disabled
* Boot Sequence : XIP w/WAIT (MUX2) -> UART0 -> SPI0 -> MMC0
ROM: Current tracing vector, word 1 = 0x0000907f
* Bit 0 : [General] Passed the public reset vector
* Bit 1 : [General] Entered main function
* Bit 2 : [General] Running after the cold reset
* Bit 3 : [Boot] Main booting routine entered
* Bit 4 : [Memory Boot] Memory booting started
* Bit 5 : [Peripheral Boot] Peripheral booting started
* Bit 6 : [Boot] Booting loop reached last device
* Bit 12 : [Peripheral Boot] Device initialized
* Bit 15 : [Peripheral Boot] Peripheral booting failed
ROM: Current tracing vector, word 1 = 0x00001000
* Bit 12 : [Memory Boot] Memory booting trial 0
ROM: Current tracing vector, word 1 = 0x00011004
* Bit 2 : [Memory Boot] Memory booting device XIPWAIT
* Bit 12 : Memory booting device SPI
* Bit 16 : Peripheral booting device UART0
ROM: Current copy of PRM_RSTST = 0x00000000
ROM: Cold reset tracing vector, word 1 = 0x00000000
ROM: Cold reset tracing vector, word 1 = 0x00000000
ROM: Cold reset tracing vector, word 1 = 0x00000001

Can anybody tell me where is the issue?
Problem is with boot loader code or with nor detection?
Thanks & Regards
