Programming applications to a microcontroller can take a lot of time, especially if the application is large, the storage device is external memory and the data rate is slow. Possible solutions Minimize download time - general settings Check the frequency of the debug interface and set up ...
Using dedicated initialization scripts, winIDEA can temporarily unprotect (and resume) Program Flash (PFLASH) Data Flash (DFLASH) Boot Mode Header Location (BMHD) before performing flash read/write operations into these areas. Flash protection password can be also entered as a script param...
When an active External Watchdog / System Basis Chip (SBC) or Internal CPU Watchdog is not serviced properly, i t can cause problems such as: Unintended reset during Flash programming or Mass Erase operation Error 258:Failed to initialize debug session BlueBox loses control over the CPU af...
When trying to perform a Mass Erase of the chip, you get an error, e.g. UMI error. Formass erase to work, the CPU should be stopped. In case you have a multi-core device, the non-primary cores should be stopped as well. Possible solutions Enable theAllow mass erase option Enable this optio...
Possible causes and solutions CPU reset caused by either External Watchdog circuitry or internal CPU watchdog Disable all reset sources during debugging to resolve the issue. More information is available in Active Watchdog issues . F1H, F1Kx: UMI Error R_FCL_ERR_FLMD0 FLMD0-Pin not at hig...
Work Flash is a flash memory used to store data (code storage for user application execution and local data storage/update for SoC-based systems). Work Flash is a part of the eCT Flash. Reading from a Work Flash that is still in an erased state will result in random data in the Memory Wind...
Data flash size of S32K3xx can change depending on Hardware Security Engine (HSE) firmware usage. Flash can have 3 different configurations: HSE firmware usage feature flag is disabled (no HSE firmware) HSE_B firmware usage feature flag is enabled (Full memory HSE firmware - HSE_FULLMEM) A...
When programming Flash memory of the S32K344 SoC using winIDEA version 9.21.109 or older, an error may occur, preventing you from programming the FLASH memory. Possible errors: Error programming UMI error Error loading monitor Possible solution Download the latest winIDEA build .
Most common reason is using authentication keys when partitioning the FlexRAM to EEPROM. Authenticating and removing this authentication by using CSEc keys is not supported by winIDEA. The partitioning can only be reversed manually. When no authentication keys are used , the EEPROM section...
If any issues with Cypress Traveo II occur, e.g.: Debug connection fails to establish Reset fails Flash programming fails Attaching to a core fails etc. follow the below procedure to troubleshoot. Possible solution 1. Enableloggingvia Help | Support | Log . 2. Check activity (27) EVE . 3. ...
Two different applications (A and B) are added into a winIDEA workspace. Application A is debugged and then Application B is downloaded and debugged. Once the Application B is downloaded the core is not stopped on the correct reset vector. Running the core from this state results in Hard F...
The TMS570 devices feature a Flash memory with optional ECC (Error correcting code) memory generation. ECC is generated in the ECC dedicated sectors, which are separated from the main Flash memory and can be programmed automatically or manually. Solution To be able to program your own ECC ...
Possible solution 1. Select Debug |Prepare to Attach . 2. If using Hot Attach, follow the Hot Attach procedure to safely attach to the Target. 3. Select Hardware |Scripts |Unsecure (can also be Chip Erase or similar). This operation needs JTAG/SWD debug port to be accessible. Devices, wher...
winIDEA checks if the start address from the Symbol file (ELF file) points to the same address specified in the STAD (Start address) field of any valid UCB (UCB_BMHDx_ORIG or UCB_BMHDx_COPY, BMHDx for x=0, 1, 2, 3). If it doesn’t, FLASH programming is rejected and a warning appears: Error ...
When the ICUM is enabled flash erase and program operations are not possible. ICUM-protected setup requires a custom procedure to perform a download. Note that disabling and re-enabling the ICUM is not necessary if a download files' image is unchanged. Python scripts are available per requ...
The UCB Flash must be writable to configure the debug password protection. Using this procedure you may lock the device! Possible solution 1. Configure winIDEA to use a password via Hardware | CPU Options | SoC. 2. S et a password. Refer to the winIDEA Help Password protection chapter for ...
When running the code after the download, it never reaches the main function. FLASH programming doesn’t report any verify error. Possible solution: Simple manual Mass erase via Hardware |FLASH |Mass Erase before debug download may solve the problem already. Most probably the application re...
With devices that are supported by UMI,we often encounter UMI-related errors when performing a Download, writing through the Memory Window, or even performing Mass erase . This topic explains the most common possible solutions and UMI errors, both reported by the monitor(running on the tar...
Check that the Flash memory is not secured or perform a special Unsecure operation (this erases Flash content). This can happen either by intentionally or accidentally writing to the memory locations managing the Flash security levels. Possible solutions Perform Reset action If a device us...
Before performing a FLASH download, winIDEA verifies if the Entry point address specified in the Symbol file (ELF file) matches the Application start address specified in the first valid RCHW record of the download image. If this doesn't match, FLASH programming is rejected and a warning i...

The scripts TC3xx_PFLASH_Inject_ECC_error.py and TC3xx_DFLASH_Inject_ECC_error.py , which are distributed with winIDEA, program a memory page to either PFLASH (address 0xA0000000) or DFLASH (address 0xAF000000).Then they turn auto ECC code generation OFF and use the same codefor reprogramm...
When Alternate Flash Programming Interface is set, only the HSM core has access to HSM code and data flash. Erased HSM code flash does not contain valid HSM boot headers, therefore HSM core remains in reset state forever, and flash monitor cannot be executed there. As a consequence the HSM...
The granularity of the erased section depends on the target device. The smallest size of Flash memory that can be erased is defined by the Flash sector size. This Technical Note describes how to erase a part of a Flash memory with a Python script. A Python script example is attached to thi...
To increase the Flash programming speed, you can use initialization files from pre-configured winIDEA Workspace Examples. Solution: 1. Download winIDEA Workspace Examples . 2. Select a suitable workspace. 3. The initialization file is by default added in Hardware menu / CPU Options / Initi...
