Hi
I had the stm32f746G-disco development board laying around, after while I wanted to try some application, during flash I got warning that my st-link firmware was old, I wanted to upgrade it but failed during upgrade, anyway it was very old firmware. Well I had another st-link at hand, I have connected it to the SWD port on the dev-kit, *** me I thought it is connected to stm32f7 but after pressing erase flash I saw the connected MCU is stmf103, well I accidentally erased the st-link, long story short it was a *** mistake.
I have been searching online there are lots of suggestion, I am very confused, is there a way to recover the on board stlink. Because there is no jumper or pin that exposes SWD/JTAG pins of stm32f7, I need to recover it.
I have tried "java -jar STLinkUpgrade.jar -d8_d32_msc_br -force_prog" with stm32f407 nucleo board but no chance.
Any help appreciated thanks.
