[GitHub] [incubator-nuttx] juniskane opened a new pull request #4469: arch/arm/src/stm32l4/stm32l4_flash.c: fix FLASH_CONFIG_I to use dual-bank access

[GitBox <gi...@apache.org>]

juniskane opened a new pull request #4469:
URL: https://github.com/apache/incubator-nuttx/pull/4469


   ## Summary
   CONFIG_STM32L4_FLASH_CONFIG_I for 2 Mb STM32L4+ devices incorrectly used page size for single bank mode while flash driver supports only dual bank mode, which is also the default for these chips when they leave ST's factory. Older STM32L4 chips do not use CONFIG_STM32L4_FLASH_CONFIG_I.
   
   Also replace incorrect comment with clarification, what parts use single bank and which use dual bank mode in STM32L4/STM32L4+ universe. (The description here is likely not complete!)
   
   ## Impact
   up_progmem API broken on all 2 Mb STM32L4+ chips without this.
   
   ## Testing
   Tested with STM32L4R5AI
