STM32G0B0: Errors in RM0454 regarding Flash ?

Split from STM32G0B0: RM0454 link out-of-date ? - this is a new topic raising issues in the document itself.

Hi @Amel NASRI ,

Thank you for your quick answer.

I have however encountered a few errors in that RM0454 Rev 5 that are different/fixed in RM0444 Rev 6. For example, the following is all done on an STM32G0B0CE (512kiB) rev Z.

• Erasing a flash page (page 78/989) PNB's limit should be 128 so it stays limited to the 256KiB of the selected bank using BKER. A higher value (for example 256+) errors the flash controller.
  If this is correct, the following image should also be incorrect (Table 9, pg 55/989)
  
  
  and be changed to
  
• Another issue that I encountered is that the 512kiB STM32G0B0CE sometimes bricks when attempting to change the option byte DUAL_BANK (pg 81/989)
  

  I believe this should also be as in RM0444, 512kiB devices always operate in DUAL_BANK mode.

  

Have I looked over something that caused me these issues? Or could you confirm that these are indeed errors in RM0454?

Hope to hear from you soon!

Hi @massimogPVS ,

Please let me check and confirm whether your assumption about missing updates in RM0454 compared to RM0444 is correct.

I have submitted an internal ticket on this topic: 227689 (this is an internal tracking number and is not accessible or usable by customers).
