Hello Vaibhav, I did register dump for the OSPI register values for the case that ospi_flash_diag_main() is able to read the ID register, and the case that the same code fails to read the ID register after adding flash config in sysconfig. The register values are exactly the same. Today, I got the approval to share the related SPI config code and example.syscfg via Zoom session without recording only. Thanks, Hong

Forum Post: RE: LP-AM243: Boot error.
Hi, I am assuming you are using CCS. Did you try DEV BOOT MODE (11110000)? If so same issue? If DEV BOOT MODE works then you can follow steps to load DMSC FW and initialize the SOC ( loadJSFile "C:/ti/mcu_plus_sdk_{soc}_{sdk version}/tools/ccs_load/am243x/load_dmsc_hsfs.js" Or, you can follow AM243x MCU+ SDK: EVM Setup (ti.com) to flash SBL NULL, and after successfully flashing it, boot from QSPI and load your application *.out from CCS without running load_dmsc_hsfs.js thank you, Paula

Are you running loopback or echo? They require different jumper settings.

Forum Post: RE: AM2432: Question regarding MULTI_CONTROLLER setting in sysconfig for SPI
If we have it in single controller mode, we can talk to the chip. If we put it in multi mode and don't even define any more channels (so just the 1st one), we can no longer talk to it.

Forum Post: RE: TM4C129XNCZAD: How to switch from using IQmathLib to using hardware floating point capability
I checked, and this option is specified in my project already. So if this option is specified as you have directed, the compiler will do what it needs to do and prefer hardware floating point support over the IQmath that is also listed in the include options?

Forum Post: RE: TM4C129XNCZAD: How to switch from using IQmathLib to using hardware floating point capability
I think it depends what you are trying to achieve. If you are simply doing simple floating point operations like multiplying some floating numbers then I believe the integrated hardware floating unit will do the job fine. If you have some routines that are used in computationally intensive real-time applications where optimal execution speed and high accuracy is critical then you can still use IQMath library, Refer to the IQMath user's guide for details. e2e.ti.com/.../SW_2D00_TM4C_2D00_IQMATH_2D00_UG_2D00_2.1.4.178.pdf

Forum Post: RE: F28M35H52C: Error 1170 after setting CSM Password and GRABSECT values
There is no "Wait-In-Reset" option in the debugger configuration for the Blackhawk XDS200 debugger I am using. I did try all the options related to holding the device in reset until the debugger is connected but no success. This is a custom board so I don't have access to the boot option pins. Unless there is another way to get to that boot option? Finally, I have NOT set a ECSL password. Only a CSM password and the GRABSECT register settings. Next step? --Keith

Forum Post: RE: TMS320F28335: Guidance on Implementing Custom Bootloader for TMS320F28335 Controller
Hello Dipak, Unfortunately, this device only inherently supports items 4 and 8 on your requirements ( as per datasheet Features ) , so the rest are not supported by the hardware and/or need to be implemented by the user. For example, Secure Boot is only available on newer devices . However, we have a Serial Flash Programming Application Note that you can reference for item 4 and there's example code located in C2000ware SDK. The serial flash kernel example can be found at \device_support\f2833x\examples\f28335_flash_kernel Regarding general information about custom bootloaders, the Boot ROM source code (device bootloaders) is available in C2000ware at \libraries\boot_rom\f2833x\v2_0\rom_sources\source. These can be referenced when developing your custom bootloader. Warm regards, Matt

Okay, unless you tell me otherwise, I'm not going to change anything. The program is just doing multiplication and division. I thought maybe I had to remove any reference to IQMath and use a new include file or something like that.

Hi, For the FlashAlignCombineToggle Setting (set to true), it is related to the Settings & Utilities -> Performance settings section of the Flash Plugin. In generating your .out file, the linker command file alignment size, you can try to use an alignment value of 0 ( ALIGN(0)). Thanks, Charles

Forum Post: RE: LAUNCHXL-F28379D: LAUNCHXL-F28379D
Hi Chirag, How do you connect DACVAL register to CANIFDATA register? Have you check the IFDATA register to make sure the data is copied to IFDATA correctly. After the data in DACVAL is copied to IFDATA register, you need to enable the TX request and write the message number to CAN CMD register to trigger the message transmission.

Forum Post: RE: TMS320F28P650DK: Problems with ADC SOC EOC IRQ generation. ISR should be entered after specific SOC EOCs in a SOC chain. Instead ISR is only entered after all SOCs in that SOC chain are sampled.
Hi Martin, At which point in the ISR did you set the breakpoint? Also can you check the value of TBCTL.FREE_SOFT field? Value of this field should be 0 so that any breakpoint would stop the time base counter. Another alternative to setting up the breakpoint in CCS is to write an ESTOP0; macro at the line you wish to put a breakpoint. My guess is the counter is probably not reflecting the current value in the register. Seems like you want to profile the exact conversion times for the SOC combinations for your control loop. You can also do this with GPIO toggles and observe the toggle duration from a scope. GPIO function GPIO_writePin() will set the output of a GPIO provided that the GPIO is configured as an output. This function takes very few clock cycles to execute so it is one reliable way to profile time duration between different points in your code. Regards, Joseph
