Bootloader information discrepancy

[HWidj.2]

Reference Manual for STM32H72xxx/73xxx (RM0468), section 2.6, says that the embedded bootloader can be accessed via I2C1, I2C2, I2C3, I2C4 and SPI1, SPI2, SPI3, SPI4, however AN2606 only lists I2C1, I2C2, I2C3 and SPI, SPI3 as the working I2C and SPI interfaces used.

I didn't notice any discrepancy with the other interfaces.

Can someone help to clarify?

Hello @HWidj.2​ ,

AN2606 is correct.

For STM32H72xx/3xx, the bootloader have I2C1/I2C2/I2C3 and SPI1/SPI3/SPI4 (no SPI2).

Thank you for noticing that. The RM0468 will be fixed in the coming releases.
