Hi All,I have two applications Bootloader and main application. I'm using UDE STK4.10 to program the board. I want know How I can load bootloader with out erasing the Main application flash memory and same for the main application write. while updating application how i can protect my bootloader code from the erase process. Thanks Basava

ST,Why can't I find _any_ info this on this part ... ? Is it possible to make a request somehow to get datasheet ???If its a custom part, does it mean that no datasheet will be provided?

I am implementing UART transmission in SPC560B50L1. Due to modest description in manual, I have some detailed questions:I set UARTCR[TDFL]=3, set TXEN and fill BDRLs registers, starting transmission.What is the exact moment when the DTF flag will be set? On which edge of which byte transmitted by UART?2. Can I access (read or write) BDRL registers before DTF flag is set? How does modification of BDRL registers affect transmission?3. Is it possible to interrupt pending transmission? Like in the middle of byte being transmitted.

Default linker script created with new SPC5Studio project (SPC560BCxxx in my case) aligns code on 16-byte boundary.This is a part of default linker script (application.ld/user.ld): .text_vle : ALIGN(16) SUBALIGN(16) { *(.text_vle) *(.text_vle.*) *(.gnu.linkonce.t_vle.*) *(.vletext) "*(.vletext.*)" "*(.ghs.linkonce.t_vle.*)" } > flash   .text : ALIGN(16) SUBALIGN(16) { *(.text) *(.text.*) *(.gnu.linkonce.t.*) } > flash   .rodata : ALIGN(16) SUBALIGN(16) { *(.glue_7t) *(.glue_7) *(.gcc*) *(.rodata) *(.rodata.*) *(.rodata1) } > flashAre there any contraindications to change alignment to 4-byte based?Since my program contains a lot of tiny functions, I waste a lot of memory space between these functions.

Hi All,I am unable to connect target to the UDE.1)Is there any necessity to install virtual Com port drivers for debugging with UDE-STK-PLUS debugger apart from the drivers provided by the UDE software ?2) How to integrate SPC5 studio with UDE-STK-PLUS ?3) Also, please share  JTAG PIN details of the SPC5-UDESTK-PLUS Debugger. So that I can verify the target connection with UDE-STK-PLUS.Thanks in advance.

I am able to switch between the banks. But writing a software in the banks is failure one.

the target board that im using is custom made which is properly working with lauterbach debugger.

Hi,I have several projects in SPC5Studio and I want to have common files shared by them, in order to modify these common files only once. So I'm trying to use linked files. I have introduced a linked folder in my project by selecting:New project/Advanced/Link to alternate location (Linked folder)/BrowseThe folder is included as linked folder. The problem is that when I build the project I get an error, because common files are not found.What am I doing wrong? Is this the right way to have common files shared by several projects in SPC5Studio?Thank you in advance for your help.

Hi,I am able to work on ADC0 and ADC1 in separate code ( LED11 flashes properly as per the analog signal). But when I initialise ADC0 and ADC1 in the same code, LED11 AND LED12 flashes as per the analog signal at ADC1.(I am using ADC sample code with addition of ADC0 , no error program compiled properly) Please help me to resolve the issue.Thanks and Regards,Pradnya

Hi All,We are using SPC560pxx series development board and it is configured with SPI,CAN,UART,ADC,DMA,PWM,ICU and other modules.We initialized the PWM, it's running proper for few seconds. But after some time, PWM stops generating interrupts. We checked it by toggling GPIO in the ISR.We have some confusions to understand it.  1. How the controller is ignoring PWM interrupt?2. How we can make user controller should handle all the interrupts. 3. How we can sequence the ISR handling?Please help me to solve this problem.Thanks,Basava.

Hello, there's problem when trying to build the project (Regardless which of the Web Motor Control Demos I choose).The steps I made are:1.) Import samples from application2.) Choose one of the motor control applications3.) Generate the SPC5 Application4.) Build the SPC5 ApplicationThe last step generates following error message:./components/spc56xx_web_motor_control_component/lib/System_Drive_Params/src/Spc5xxx_MC_it.c:48:21: fatal error: pal_lld.h: No such file or directory #include "pal_lld.h"Which is a bit strange, since I didn't make any changes to the configuration.Can you please help?

Hi All,I'm working on the SPC560Pxx series development board and using SPC5 studio application to build my code, I have uploded my IDE. Since it is update, generate option is the IDE is showing below messages. Could you please anyone suggest me how to solve this issue OR let me know which sofrware I need to update and solve this issue,thanksBasava.

Hi, I am trying to use SPC5-FLASHER, in particular the version SPC5FlashProgrammer2.7.9, in order to  manage the Flash using the BAM/BAF functionality, but I am having troubles. Firstly, the target board I am employing has the microcontroller SPC570S40E1. This one isn't present among the options in the "Configuration" tab, so I was wondering if the device SPC570S50, which belongs to the same family of mcus, is a good choice or not.Futhermore, I programmed the target board with the project “SPC570Sxx_RLA Bootloader Application for Discovery�?, which I obtained in the following way:-       I created a new project File/New/ SPC5Studio import wizard/-       I selectedthe family SPC57 -       I selected the evaluation board SPC570S50L1DISP-       I selected the Application “SPC570Sxx_RLA Bootloader Application for Discovery�?At startup the boatlode

HelloI am looking for a library and/or code examples of DSP and mathematical functions using the SPE for speed optimization. The one referred in ST is discontinued and not available.Thanks in advance.caio@canoo.com

When I use the osalThreadDelayMilliseconds(200) function the software always remain in this loop while (osalsystime < current + ticks) { }i check the software is only LED blink can any one know what happen to the OSAL library ? I use RLA Library

We are writing 2kbytes of Data into the dataflash at the rate of 8bytes/1ms before ECU enter into sleep state.When we do this activity several times, DATA Flash got corrupted and ECU stops working.We had followed document en.DM00068954 , for our implementation.Could you please help us resolve this issue on priority?

There is a hadrware documentation request for SPC584C70E3 datasheet, getting started, reference design and any other similar documents available for sharing with a key customer (NDA is also signed). Please let me know how can I get them. Thanks in advance.

Hi All,I'm using SCP560P50L controller and I tried to use UART communication in my project.I did configured the code and pins related to the uart.But I'm facing issue in below lines of code.In the lldconfig.h file SPC5_LINFLEX1_SETTING    default values is set with SPC5_LINFLEX_MODE_LIN. I change it to  SPC5_LINFLEX_MODE_SERIAL. But if regenerate the code SPC5_LINFLEX1_SETTING    will change it to default value.#define SPC5_LINFLEX1_SETTING        SPC5_LINFLEX_MODE_SERIALHow to retain my changes?Please help me to understand this issue.Thanks,Basava.

Hi All,I'm developing a secondary bootloader to load my main application to flash memory. I used example bootloader code for my controller SPC560L3. I have some questions related to the linker files. How I can create separate linker files for my Bootloader and application code.As shown in the below pic, Bootloader code starts from 0x0000 address and ends at 0x8000.Application starts from 0x8000 address.How I can create .ld file to use these addresses. How to shift my vector table address for main application 0x8000.Please help me with any example code or suggestions.Thanks,Basava.

Hi All,I'm searching for example Bootloader code for SPC560P50L3 controller ( 100 pins package). I tried import from the example code in SPC5 studio, but it is for a SPC560P50L5 controller. How I can convert this code SPC560P50L35controller ( 144 pins package). I need to match the controller pin mapping Is there any way to convert this code to 100 pins package controller OR is there any bootloader example code available for SPC560P50L3 controller, where i can find it.Please suggest me the link or method to convert it.Thanks,Basava.

I read the manual and I could not find the location of the library to download. Does anyone know where it is located or if there is? Is it available through a third party or from another website? Is there an equivalent one somewhere else?Any help would be greatly appreciated.Thanks!caio@canoo.com
