I have a board of SPC560B. I need to make a BootLoader. I want to do that:   the JMP_ADDRESS is 0x40000 PowerON--> running BootLoader at 0x000000 in flash.--->delay 3000ms-->if (update cmd ==false)----->  (*(AppFunctionType)(JMP_ADDRESS+8))(); // jump to app and should not back Is that ok?   Why do all people develop BootLoader in RAM for… (Show more)

 I have an application where I need to enable two PWM outputs. They need to have the same frequency but different duty cycles  I have got PWMA0 and PWMA1 working but I am not able to get them synced together. There is a 9.2us difference in switching between A0 and A1.  I tried playing around with the FORCE_EN register and but was unsuccessful.… (Show more)

Hi  I trying to use the PIT to generate an interrupt every 1.7uS to toggle a GPIO and it does not seem to be working well.    I have a sysclk of 64MHz. Im using PIT1 and setting the LDVAL register with a count. Now the timer seems to be working well for a count of 200000 which corresponds to an intrerupt time of 5uS.  But any value less than that… (Show more)

Hi ST expert,   I am trying to use SPC5 as a multi-channel PWM controller. Normally for this kind of application, the duty cycle calculation will be done in an interrupt. For 100kHz PWM, the allowed interrupt duration is <10uS, for example 8uS max. The rest of time (10uS-8uS=2uS) should be reserved for other processes, such as communication etc.… (Show more)

Hello I am trying to implement a I2C driver on a SPC58EC. The problem I am facing now is that I cannot get the signal output on the pads correctly. IBSR.IBAL is immediately set when I try to generate a START condition. I am suspecting my pad configurations (PB8 + PB9) are incorrect but I have no idea what are the correct values.   What are… (Show more)

hello team,when i wakeup from standby mode always system reset was generating.My SW not jumping to address what i mentioned in CADDR register .when i debug the issue found "F_FCCU_HARD" Flag was enable after wakeup. is there is any method to disable this Flag permanently? if yes.please share some sample code to handle FCCU Module? Thanks in… (Show more)

Hi,I'm developing an I2C driver for a SPC560B54L5 micro, and I have problems generating the stop bit.At the end of a write operation, I run the following pseudo code:   while  (0 == IBSR. IBIF) { /* wait */ }   IBCR.MSSL = 0 /* generate stop bit */   while (1 == IBSR.IBB) { /* wait */ }After a few successful transfers (including the stop condition… (Show more)

I have a simple for loop that should ideally run 20 times, inside which I toggle an LED. When I debug this code on my SPC56EL controller (on a daughter board which is mounted onto the XP56 motherboard) WITHOUT hardware breakpoints, it toggles only once and exits the main handler (confirmed this behavior). But when I add breakpoints in the loop, it… (Show more)
