Hi team,
Here's some issues from the customer may need your help:
The customer would like to know how to store data to a specified memory, as the following codes show, no memory allocated to variable mydata0.
The code is as follows:
/*----------------------------------------------------------------------------*/
/* Linker Settings */
--retain="*(.intvecs)"
/* USER CODE BEGIN (1) */
/* USER CODE END */
/*----------------------------------------------------------------------------*/
/* Memory Map */
MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x0017FFE0
FLASH1 (RX) : origin=0x00180000 length=0x00180000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0003EB00
MY_NEW_RAM (RW) : origin=0x08040000 length=0x00001000
/* USER CODE BEGIN (2) */
/* USER CODE END */
}
/* USER CODE BEGIN (3) */
/* USER CODE END */
/*----------------------------------------------------------------------------*/
/* Section Configuration */
