Hi Adrian,

We have set SW4=00010010 and SW5=10100100.

                                      Virtual bank select

SW5[4] BANK_SEL0    • 000: No change (default value)

SW5[5] BANK_SEL1    • 001: Virtual bank #1

SW5[6] BANK_SEL2    • 010: Virtual bank #2

                                      • 011: Virtual bank #3

                                      • 100: Virtual bank #4

Hi Adrian,

We have tried both cases with bank select(001 and 100),but still no results.

hi Adrian,

We have tried to flash uboot and rcw to bank 4 of nor flash.We were successful in writing uboot and rcw to the locations specified using flash programmer.However we are not able to boot from bank 4(we tried flashing with nor boot from bank 0).Below is the log of location we wrote.

What's the value for SW4 anf SW5 on your board? It should be SW4=00010010 and SW5=10110010, for booting from NOR, bank4.

Adrian

[addiyi]

Did you have the board set for booting from bank4, when you erased bank4?

Adrian

[nikhilprakash]

We tried it with both bank 0 and bank 4 with SD card booting.

[addiyi · Accepted solution]

Try to set the board to boot from NOR bank0 and using flash programmer erase uboot from offset 0x4100000.

Adrian

[nikhilprakash]

Hi Adrian,

We set sd card booting and selected bank 0 by switch settings and then we wrote to bank 4 of nor.It worked.

Thanks

[nikhilprakash]

Thanks Adrian, will try it...

First you should download CW4NET and install CodeWarrior for ARMv8. Then, go to Freescale\CW4NET_v2016.01\CW_ARMv8\ARMv8\Help\PDF\ and in ARMv8_Targeting_Manual.pdf, Chapter 7, Flash Programmer, you can find helpful information.

Hi Adrian,

We are trying to erase the nor flash bank 4(offset 0x4000000) rcw&uboot portion using flash programmer.But it is not working.Is this the correct way to do??Pls help.

[addiyi]

The address is correct. Could you provide the error message?

Adrian

[nikhilprakash]

Hi Adrian,

Actually we are trying to erase the uboot portion from bank 4 which was programmed earlier.In the flash programmer we tried to erase that portion.We were successful in erasing that section as it showed no error.But when we tried to test the bank 4 it is still booting.That is even though we erased(erase was successful) the uboot portion it didn't work.Is there any other thing we need to do?Whats the issue??Pls help.

[nikhilprakash]

Thanks Adrian will go through the document mentioned.
