POR boot

[arichadav]

Hi,

I have an interesting problem related to power up boot of a self made P2041 board.

I configured the chip to hard coded RCW that supports 16b NOR Flash (cfg_rcw_src[0:4] = 1_0010).

however, once POR signal is negated no FLASH chip select signal is asserted and the P2041 remains hang.

one can access its registers via JTAG debugger if needed.

any ideas why there's no chip select?

thanks.

Please check the status of LA[18:22] during POR. These pins must NOT be pulled down during power-on reset, otherwise may cause processor halt and LCS not toggling.

I'm debugging  a customer P2041 board.

There're issues in P2041 boot up stage,  following test cases:

Test case1: cfg_rcw_src[0:4]配置字 01100 (Nor flash 8bits width)， elbc bus output LCLK0 signal at 6.25MHz, elbc cs0 will output four valid chip select signals ( but p2041rdb output eight chip select signals  under this case)

In test case1 ,because elbc bus output LCLK0 signal at 6.25MHz,  Does it mean the clock tree for elbc ok? 

Test case2: cfg_rcw_src[0:4]配置字 01101 (Nor flash 16bits width)， elbc bus output LCLK0 signal at 6.25MHz, elbc cs0 will output two valid chip select signals ( but p2041rdb output four chip select signals  under this case)

Test case3: cfg_rcw_src[0:4] 10000 (hardcode rcw)，RESET_REQ_B is always assert high level '1', it seems the cpu is always at reset status,  HRESET is always at low level "0", Asleep is at high "1".

Test case4: cfg_rcw_src[0:4]配置字 00110（SDHC)， dessert PORESET_B,  SDHC_CLK and SDHC_CMD will output some signal

Test case5: cfg_rcw_src[0:4] 00000 (I2C normal), program I2C eeprom with rcw word , after cpu loaded rcw word from eeprom ,  the HRESET is also at low level "0", Asleep change to  high "1" at the end of load I2C eeprom. But MCKE, MCK is always at low "0". 

The behaviour corresponds to following   Some of the I/O drivers are enabled; specifically, those pins associated with any interface potentially usable as the source of RCW data. All of the DDR I/Os become
enabled at this point (though MCKE, MCK, MODT are enabled from the beginning).
The ASLEEP signal is also enabled at this point.

P2040 QorIQ Integrated Multicore Communication Processor Family Reference Manual,   4.6.1 Power-on reset sequence     stage 8.

I use the codewarrior tap to debug the on board CPU,  create the p2041 ram attached project to connect to the cpu, get the following message: the CPU type is P2041NXN7NNC
