In Renesas RH850, CS+ IDE , DCU cannot be accessed it shows error(E1203184) while Flashing from E1 emulator, even when all connections are correct. How do I resolve this issue?

There are basically two way to change the UART baud rate at run-time. It depends how you allocated the UART. If you allocated by PDL-method (ie. In the PSoC Creator TopDesign or Modustoolbox Device Configurator [design.modus]) then use the PDL SysClk API calls: Configure Baud Rate To get the UARTRead more
There are basically two way to change the UART baud rate at run-time. It depends how you allocated the UART.
If you allocated by PDL-method (ie. In the PSoC Creator TopDesign or Modustoolbox Device Configurator [design.modus]) then use the PDL SysClk API calls:
To get the UART to operate with the desired baud rate, the clk_scb frequency and the oversample must be configured. Use the SysClk (System Clock) driver API to configure clk_scb frequency. Set the oversample parameter in configuration structure to define the number of the SCB clocks within one UART bit-time.
* For clk_peri = 50 MHz, select divider value 36 and get SCB clock = (50 MHz / 36) = 1,389 MHz.
* Select Oversample = 12. These setting results UART data rate = 1,389 MHz / 12 = 115750 bps.

Cy_SysClk_PeriphSetDivider (UART_CLK_DIV_TYPE, UART_CLK_DIV_NUMBER, 35UL);
Cy_SysClk_PeriphEnableDivider(UART_CLK_DIV_TYPE, UART_CLK_DIV_NUMBER);
Refer to the technical reference manual (TRM) section UART sub-section Clocking and Oversampling to get information about how to configure the UART to run with desired baud rate.
If you allocated the UART by the HAL-method use:

I have recently been toying around a Renesas RH850 and would like to know what virtual channels are useful for ADC? I understand you can assign them to any physical ADC channel, but what is there purpose for that? Why not just read the physical channels?

The virtual channels allow us to arrange physical channels in a scan group in any order. Since each virtual channel may be assigned to any physical channel, and scans are in numerical order by virtual channel. We can also assign virtual channels to multiplexed analog inputs. Read more

Hello Pallavi, For that first download self check programm of E1 emulator from Renesas website, and confirm is it passed and ok to use.
