Hi,I am working on SPC58NG84E7 bootloader. Everything works fine - I have BL code(at 0xFC0000) which jumps to the APP location 0xFD0000 after waiting for 10sec after startup and executes the code there. Both codes are without SWT.Issue - But when I added SWT component to BL, on powerOn BL is not running. swt_lld_stop() is called before jump.If I start the BL through UDE debugger application it executes BL, jumps to APP, executes APP code, but then reset from APP and entering into BL is not working.This issue remains in APP with SWT and without SWT both.What could be the issue here?Regards,AM

Hallo Everyone,If I setup two TOM channels with the TOM module clocked at 100MHz: (10nSec)GTM clocked at 100MHzCMD.CFGU.EN_CLK0 = trueCMD.CFGU.CLK_DIV0 = 1TOM0 module enabledTOM0_4 source clock = CMU_FXCLK0TOM0_4 period = 10000TOM0_4 duty = 5000TOM0_3 source clock = CMU_FXCLK0TOM0_3 period = 10000TOM0_3 duty = 4800[EDIT]Use an oscilloscope with sufficient speed and sampling buffer.I was using a rough tool which was not allowing me to see into deep.

Hello,I am working on the bootloader, trying to flash only 256 bytes. So, before flashing, erasing the block 0xFF0000. There is already some data in this block. But erase is not happenin, even if FlashErase() returns 0 and FlashCheckStatus() also gives opResult=0. Also when I check memory, it still shows the same data and not erased.Following below steps to get flash block erased-#define LOWBLOCKSELECT 0x00000100U#define MIDBLOCKSELECT 0x00000000U#define HIGHBLOCKSELECT 0x00000000U/* Unlock the requested block for Erase operation */ nLargeBlockSelect.firstLargeBlockSelect = 0; nLargeBlockSelect.secondLargeBlockSelect = 0; SetLock(&FLSHM_ssdConfig, C55_BLOCK_LOW, UNLOCK_ALL_BLOCKS);   irqIsrDisable();   /* Erase the requested block */ Return_Val = FlashErase(&FLSHM_ssdConfig, C55_ERASE_MAIN, LOWBLOCKSELECT, MIDBLOCKSELECT, HIGHBLOCKSELECT, nLargeBlockSelect); if(Return_Val == C55_OK) { while(C55_INPROGRESS == FlashCheckStatus(&FLSHM_ssdConfig, C55_MODE_

HiCan any Mcu detect a 5ns wide pulse? Is MCU clock speed important in this case? Or are MCU pin speeds important?Are MCUs capable of detecting such a low amplitude signal?Many thanks for any guidance provided...

hello everyone;I’m trying to send some SPI command by SPC560 microcontroller. During the main program I must send a special code regularly, for example I must send the code “0xAAAA�? and “0xBBBB�? every 20mS. Actually when the main program is running, if 20mS happened, the main program must stop and send code�?0xAAAA�? and then come back to the last point of the main program. I try to do this project with PIT, but I can’t reach to desired result. how can I solve this problem?with regardsBahareh

Hi there,I was looking for the current limit on the 5v and 3.3v pins of the SPC58E80E5 board (I check in the user manual) but I can't figured out.Which ones are they? Where I can get this information?

Hi I have problem with LINFlex5 calling 'Stuck at Zero Flag' interrupt continuously. Voltage on the pin 29 (GPIO4/E0UC4/CS0_1/LIN5RX/WKUP9) is 3.2V nevertheless. It's 100-pin LQFP version so there no other choise for LIN5RX input (using PADSEL60). I configured pin in PCR4 boyh as input or input with pull-up but to no avail.I'll be grateful for any helpRegradsPavel

HI,I have a question regarding the GPIO setup.I have setup a few pins and outputs from the pin map editor. For all of those pins, the togglefunction work without any issue. However when I try to turn them on or off using the write_pad function or the set_pad, clear_pad function it does not work. Nisal

Hi,In our project, we are using a 20Mhz external crystal oscillator. The default frequency of external oscialltor in SPC5 Studio CLock Tree editor is 40Mhz. How will I change it to 20Mhz? Please see the picture below. Br,Sreejith

Hi,When I use the low level drivers that comes with SPC5 Studio, I am facing issues with CAN reception.The Rx buffer only updates with the highest priority message. All the messages below that are ignored. I tried with FIFO and Dedicated Buffer settings, but both have the same problem.Please can you advise on how to fix it?Best regards,Sreejith

Hi All, We are using the SPC560P50L3 controller in our project. ADC0 and ADC1 are used to read 16 ADC channels.ADC0 is configured with one group with 6 channels, ADC1 is configured with 2 groups. Group1 - 6channels   Goup2 - 4channels.We need to read the ADC0 group channels at a higher rate, its conversion is called in the while loop (ADC_Handle_Grp1_Measurements), and ADC1 groups are called in the 1msec timer (ADC_Handle_Grp23_Measurements). We are using adc_lld_setup_scan_conversion() to configure the ADC0 to enable DMA to read the ADC channels with 32samples and adc_lld_start_conversion() is used to configure the ADC1 groups to read 1 sample. Since we are using 2 groups in the ADC1, the DMA configuration will be shared between 2 groups. Each group will wait until to complete the ADC interrupt to configure the DMA adc_lld_start_conversion(). Some time we are facing problems, code is calling adc_lld_start_conversion() configu

MCU - SPC560P50L5First I compile and flash RTOS serial example with no errors. then I run it. No errors were detected. same process was followed to check ADC example. There also no error were found. Then I combined both codes as follows(attached). It compiled with no errors. But it did not run smoothly. The LEDS always lit.

I have 2 questions.SPC560P50L5 and SPC563M64L5 microcontrollers from ST with which microcontrollers from NXP are compatible (in terms of functions and pins)?Can the output hex file from the MPC56 and SPC56 microcontrollers be replaced?

Please find attached the code; and screenshots of Output & Configuration settings

Hi, I am working on SPC58NG84E7 bootloader. I have BL code(at 0xFC0000) which jumps to the APP location 0xFD0000 after waiting for 10sec after startup and executes the code there. Both codes have optimization NONE(-O0). But when BL optimization changed to -Os size or any of the mentioned, BL is not jumping to the APP and continuously running the BL code.What could be the issue here?Regards,AM

Micro controller : SPC584BWe tried configuring the DMEM Processor local RAM for SPC584B Microcontroller.(Attaching the DMEM Memory layout) (We have configured it outside BAF region)We tried pushing initialized global variables to this section. We have changed the linker so that the initial values are stored in ROM. During initialisation, the initial values in ROM are not getting copied to the RAM section. StartUp code change: /* Copy data sections ** Note: the "-1" on the start and end addresses is there because ** stbu updates before storing. */ lis r3, OS_hi((_DATADMEM_START_-1)) addi r3, r3, OS_lo((_DATADMEM_START_-1)) /* Start of data section */ lis r4, OS_hi((_DATADMEM_END_-1)) addi r4, r4, OS_lo((_DATADMEM_END_-1)) /* Limit of data section */ lis r5, OS_hi((_DMEM_-1)) addi r5, r5, OS_lo((_DMEM_-1)) /* Start of initial values in ROM */ b __copy_data__copy_loop: lbzu r0,1(r5) stbu r0,1(r3)__copy_data: cmpw r3, r4 bne __copy_loopWe are also seeing that after a pow

Hi,I am using SPC584B70E3 and I want to configure some of the inputs as an ICU. However, the SPC5Studio Limits the ICU for eMIOS0 Channels 0-7 only. I cannot configure PE[0] (eMIOS0 Channel 11 or eMIOS1 Channel 13) as ICU for instance. In the Reference Manual these channels have the ability to be configured as SAIC (Single Action Input Capture) but I do not understand how that is done through SPC5 Studio.Can you help me with configuring PE[0] as an Input Capture as an example?Thanks for the help,

Hello,I normally copy an old SPC5 project and paste it with an updated version number to modify the source code. But, the copied UDE workspace is referring to older source code. Can you help to fix it?Thanks in advance.Br,Sreejith

After flash programming, the program doesn't run once I disconnect the debugger and do a power cycling. Can somebody help me to find what the problem is? I use the attached build settings for Hex file generation in SPC5 Studio.
