I have the Keil IDE with the ARM Compiler toolchain Version not enough information to list image symbols 5.02 The processor is a stm32f303 This is my error message. UART STM32F3.axf: Error: L6218E: Undefined symbol ucInputBuffer (referred from routine.o). The "ucInputBuffer" is my own variable. I have the #include "routine.h" where the "ucInputBuffer" is declared. Inside the "routine.h" file I declare the variable like shown below. extern volatile unsigned char ucInputBuffer; This is my compiler control string. -c --cpu Cortex-M4.fp -g -O0

The message says that you have not defined it... http://www.keil.com/forum/21995 Read-Only AuthorRuss Schultz Posted20-Dec-2012 17:21 GMT ToolsetARM RE: ERROR: L6218E Undefined symbol Russ Schultz 'extern' tells the compiler that there is a variable declared somewhere else that is of that type, but it doesn't actually reserve the memory. This allows code to reference variables not declared in its local scope. When the linker goes to stitch everything together and resolve the references, it's looking for the actual variable which must be declared (once and only once). You're missing the line in a C file where you declare your variable: volatile unsigned char ucInputBuffer; (Note the lack of 'extern'.) Read-Only Autho

Define symbol USE_STDPERIPH_DRIVER and define project path like so: Test your configuration. Please write the following code: #include "stm32f10x.h" // Device header int main() { } share|improve this answer edited Apr 14 at 19:43 Paul Roub 29.2k83963 answered Apr 14 at 19:24 Purgoufr 214 add a comment| up vote -1 down vote http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/14222.html This should help. Just create a dummy main() or main.c file.

Undefined symbol error when exporting from mbed to Keil µvision Hi, I don't know what I am doing wrong, but every program I export from the mbed compiler to µvision gives me tons of errors. The errors are always of the same kind. They are "Undefined symbol errors". I even get these on a simple blinky program. Here is what I get on the mbed blinky: Quote:* Using Compiler 'V5.05 update 2 (build 169)', folder: 'E:\Keil_v5\ARM\ARMCC\Bin' Build target 'mbed NUCLEO_F401RE' linking... .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol gpio_init_out (referred from main.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol mbed_assert_internal (referred from main.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol wait (referred from main.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_ADCEx_InjectedConvCpltCallback (referred from stm32f4xx_hal_adc.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_I2S_ErrorCallback (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_I2S_MspInit (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_I2S_RxCpltCallback (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_I2S_TxCpltCallback (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_DMAError (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_DMARxHalfCplt (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_DMATxHalfCplt (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_Receive_IT (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_Transmit_IT (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol I2S_WaitFlagStateUntilTimeout (referred from stm32f4xx_hal_i2s_ex.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_NVIC_SetPriority (referred from stm32f4xx_hal.o). .\build\mbed_blinky.axf: Error: L6218E: Undefined symbol HAL_NVIC_SetPriorityGrouping (referred from
