Hi 

i'm looking for how can i manage or block Fls_17_Dmu_write or other api something like that during download by UDS. 

according to the MCAL document, Fls_17_Dmu_write api is Non-reentrant. 

 

so if i download updated software to alternate address for A/B swap on runtime, i should block other access to flash. 

i'm writing an application using MICOSAR and MCAL but, I couldn't find solution in the documentation.

 

i think i should block flash api on application software level. (ex. if any ASW send flash related request, some code pend this request and after download updated SW,  

Does anyone know of a good way to prevent this at the BSW or register level.

Thanks.
