I am using STM32L562 family microcontroller. I have interfaced TCPP01-M12 with my microncontroller. I have a doubt , whether i can use this device when using UCPD in source mode, as i am unable to configure software packages for source mode(X-CUBE-TC...

Hello,We have been using NAND Flash (MT29F8G08ADAFAH4-AAT) interfaced with STM32L562 microcontroller using FMC interface. We are first trying to read the ID of the Flash using the below HAL API. if(HAL_NAND_Read_ID(&hnand1, &NAND_ID) != HAL_OK){retur...

Hello,We have interfaced a NOR flash (S26KL512SDABHN020) with STM32L562 over OctoSPI in Hyperbus mode. The Low level drivers were found from one of the forums of ST community and were ported in our code. We are unable to read/write data at the base a...

Hello,We have been using two SRAMs (CY7C1061G30-10BV1XE) & one NAND Flash(MT29F8G08ADAFAH4-AAT) interfaced with STM32L562 micro-controller on same FMC bus. We have initialised FMC and try to access SRAM1 by selecting Chip select: NE1 and Bank 1. It i...

Thanks Peter for the quick reply.Can this restriction affect the functionality in ucpd source mode? Apart from that if I have to use tcpp01 for source mode what are the work I need to put in as I have a custom stm32l5 board with same design for tcpp0...

I have old datasheet(DS12900 - Rev 4 - December 2020), in which it was mentioned that tcpp01 can be used in ucpd source mode as well as sink mode. I am attaching the screenshot . Kindly verify

Thank you for the reply. We were able to make NAND flash work by change in timing numbers and clock frequency(30Mhz maximum) for AHB bus. Thank You for your support

Hello @KDJEM.1 ,We have tried with the recommendations provided by you:1. Set the Access time as 6.2. Checked for different OCTOSPI frequencies: 4MHz, 15MHz, 20MHz, 30MHz and 60MHz.3. RDP level is already at 0 as read in Option-Bytes using STM Progra...

Hello,The above settings recommended by you have been tried out but we are unable to even read the Device ID itself.We read Device ID as 0xFFFFFF. We are completely stuck. Kindly suggest us more.
