Hi,

so, summarizing, if you cut the external reset circuit, unplug the debugger, power the board and monitor the pin RESET_B, this pin is always low. Right?

this is how it shows when i enable hardwar reset mode it connected but core is always inactive

[zambrano.luigi]

Please, could you confirm that if you cut the external reset circuit, unplug the debugger, power the board, the pin RESET_B is always low?

yes that is the issue

[kjay]

yes you are absolutely right..thats the issue..

 i cut the external reset circuit, unplugged the debugger, power the board, the pin RESET_B is always giving low..that is main problem..in discovery it is not it works well...for my circuit is gives low ..always

[kjay]

i have developed four pcb board with four differnt ic ...all got same issue..cheked power supply and reset circuit...but reset is low while i power up...i dont know what to do next..help out..

Hi,

sorry, but it is very complicated to address your issue without the hardware, also because the schematic of your board seems aligned with the schematic of our Discovery. Please, could you let me know where you are located in order to involve the local support?

hi,

i followed discovery board to make the core work..you have seen my schematic right is there anything i am missing in order to make core run...i need a minimum working configuration schematic for spc 56EL60L5CCOSR core...i checked hardware..4 times with four different board there is very low possibility of hardware error since 4 boards behaves same...so i think some problem in configuration...is spc56 and dicovery are same interns of minimum configuration or ..SPC 56 should require different config..please check my schematic and ensure i had it right interms of config of schematic...i am in india..tamilnadu state...

i found out the problem it was one of the decoupling cap.........solved it ...it is working now thank you for help ..now reset is LOW have to check with JTAG program..any way thank you.

Hi,

good news! Yesterday I talked about your issue with the local support asking him to contact you in order to check the hardware, but I'm happy to know that in the meantime the issue has been solved.
